Today, just now, I came across the latest achievement of the team led by Hu Yongsheng from the Institute of Physics, Chinese Academy of Sciences. I am really getting more and more excited as I read it. Our sodium-ion battery has completely broken through the safety ceiling of power batteries this time.
Many people may not realize the significance of this achievement. In the past, there has been a misconception in the industry that if the electrolyte is flame-retardant, the battery is safe. However, the reality is that even if the electrolyte is non-flammable, once the battery experiences a collision or overcharge, the internal temperature will soar, and thermal runaway can occur like a domino effect—if one cell has a problem, the entire pack will follow suit. This time, Hu Yongsheng's team has directly jumped out of the old thinking of relying solely on flame retardancy and has constructed a three-in-one intelligent protection system of "thermal stability-interface stability-physical isolation."
In simple terms, the newly developed polymer non-flammable electrolyte PNE is like installing an intelligent firewall inside the battery. Normally, it is in liquid form, which does not affect the normal charging and discharging of the battery at all. However, once the battery temperature rises abnormally above 150℃, it will instantly solidify into a dense barrier, directly cutting off the chemical reaction between the positive and negative electrodes and completely welding shut the propagation path of thermal runaway. This is the world's first complete blockage of thermal runaway achieved in amp-hour level sodium-ion batteries. Even at high temperatures of 300℃, a 3.5Ah cell can achieve no fire and no explosion, and the needle penetration test passed smoothly.
For our Chinese new energy vehicle industry, the significance of this breakthrough goes far beyond the technology itself. Our new energy vehicle production and sales have reached the top globally, but the dependence on lithium resources from abroad has long exceeded 70%. When prices fluctuate, the entire industry is affected. In contrast, the crustal reserves of sodium resources are more than 400 times that of lithium, with widespread distribution and controllable costs, allowing us to operate without relying on overseas sources. This is the core card for our new energy industry to achieve true autonomy and control. Previously, sodium-ion batteries have been questioned about their adaptability to passenger car scenarios, with the biggest concern being safety. This time, we have directly addressed this major shortcoming.
How long will it take for this technology to be implemented? There is a particularly crucial piece of information: all the materials used in this achievement are already mature products that have been industrialized, so there is no need to build the supply chain from scratch, significantly lowering the industrialization threshold. Moreover, Hu Yongsheng's team itself is the founding team of the domestic sodium battery leader, Zhongke Haina, which has already built a production line for billion-watt-hour level cells and will deliver the world's first mass-produced sodium battery vehicle in 2024. This year, it is also promoting the batch application of commercial vehicles with several automakers.
According to the conventional pace of the industry, I estimate that it will take 2-3 years for this technology to go from laboratory validation to mass production and being put on vehicles. If things go quickly, we will see its implementation in energy storage stations and commercial vehicle models next year, and the popularization in the passenger car field is just a matter of time.
There have always been people saying that sodium-ion batteries are merely backup options for lithium batteries, but I have never thought so. This safety breakthrough has given sodium batteries an irreplaceable core advantage. In the future, in the fields of new energy vehicles and large-scale energy storage, they will undoubtedly occupy a significant position. The progress of China's new energy industry to this point has never relied on following trends and imitation; it is through repeated breakthroughs in fundamental technologies like this that truly deserve our continued attention.
Suddenly remembered that I signed up for the futures daily live trading competition this year. Recently, I have been busy with business trips, research, and writing, so I haven't participated. When I just looked at the rankings, I was surprisingly ranked 27873 out of a total of 70597 participants. In other words, I haven't done anything and have already surpassed two-thirds of the competitors [confused]
At first, I thought Sun Ge was a fan of Chuanzi, but later I found out that Chuanzi is a fan of Sun Ge, winning the great master of learning, TACO old eatery, no, isn't Chuanzi in contact with Iran through Xiaohongshu? Why is there still a discrepancy?
#Elon Musk Supports Kimi# Recently, there has been quite a stir in the tech circle. Initially, everyone thought it was a shell game misunderstanding, but it unexpectedly turned into a highlight moment for Chinese AI. Here's what happened: the AI programming tool Cursor, which is currently gaining tremendous popularity in Silicon Valley, released a new model, Composer 2. At the time of the release, Cursor was basking in glory, claiming its performance crushed various large models. However, not even three hours later, it was exposed by netizens. A developer checking the backend code discovered that it prominently displayed the model ID for Kimi K2.5. In no time, discussions exploded online, and many people's first reaction was: after all this time, is the top team in Silicon Valley also playing the shell game? Just when everyone was in heated debate, Musk suddenly surfed into the scene and replied under that explosive post: this is Kimi 2.5. Musk's comment pushed the heat of the matter to its peak. Everyone was watching how Kimi would respond, as being exposed for underlying code like this could lead to a public relations crisis if not handled well. However, Kimi's response was quite charming; they didn’t engage in any back-and-forth or show any grievances, but instead, they openly admitted it. Kimi's official Weibo account directly posted, “Listen to me, thank you…” This response was interesting, humorously replying to Musk while also showcasing their confidence. It turned out this was not some sneaky shell game, but a serious commercial partnership between the two parties. Cursor obtained authorization for Kimi K2.5 through compliant channels and built on that to do further reinforcement learning. Such collaborations are actually quite common in the AI circle, but previously it was mostly domestic models using foreign bases; now it has reversed, with Silicon Valley’s top tools starting to use our Chinese models as their foundation. It's no wonder that netizens are exclaiming, #The Landscape of Chinese AI Has Opened Up#. We used to feel like we were chasing in the AI field, but this choice by Cursor actually illustrates a very simple truth: whoever has a usable model and solid technology will be used by developers globally. The fact that Kimi K2.5 was picked by Cursor shows that its reasoning and logic capabilities have reached world-class levels. Musk's involvement this time, on the surface, seems like a revelation, but it actually feels more like a side endorsement. A model that can attract Musk's attention certainly carries significant weight. Such healthy competition and collaboration are much more meaningful than closing the door to focus solely on self-research. AI is inherently an open ecosystem; this time, Kimi not only caught the joke thrown by Musk but also showcased a very open and confident demeanor of a large company, making it clear that Chinese AI companies are no longer just trailing behind but have the capability to provide foundational power for the world’s top tech products. The landscape has indeed opened up; this kind of confidence is much more substantial than merely outpacing a few rankings.
#Shanghai police announce new anti-fraud achievements# I just saw the set of anti-fraud data released by the Shanghai police. In 9 months, the exposure exceeded 900 million people, and the most crucial point is that “the number of fraud cases has dropped by nearly 50% compared to the peak period.” In this extremely tense battlefield of anti-fraud, being able to cut the incidence rate by half is definitely not something that can be achieved by just posting a few posters or hanging a few banners. In the past, anti-fraud was mostly about “don’t transfer money” and “be vigilant,” but now the scammers are all masters of psychology. They study human greed, fear, and loneliness. It’s actually quite difficult to counter their carefully designed scripts with boring slogans. This time, the Shanghai police are smart because they have started to play with content. I have also seen a few of those jointly launched anti-fraud short dramas, and the immersive experience of those real-life scenes is very strong. Essentially, this is about using content to counter content; scammers make up stories to deceive you, while the police film dramas to dismantle their tricks, transferring anti-fraud knowledge from legal textbooks to the short video feed area, allowing everyone to unknowingly stack a layer of protective buff during their fragmented time on their phones. There is a point in the data that needs special attention: people born in the 80s and 90s are surprisingly the key target audience. Many people think that those who get scammed are elderly individuals with poor information access, but that’s not the case. Young people are more likely to fall for scams in cash-back schemes, fake investments, and even high-tech scams like AI face-swapping, because they often feel too confident, thinking they grew up on the internet and understand algorithms and rules. However, the reality is that scammers are also iterating. When they come to find you using AI-generated audio and video, leveraging big data for precision targeting in pig-butchering scams, relying solely on experience is no longer sufficient. This combination of technological control and precise outreach actually pushes the protective barrier right in front of the users. By the time you realize the risk, the platform's intelligent warning has already stood between you and the scammers. This invisible guardianship is much more efficient than chasing after those tens of thousands of dollars after the fact. The battlefield of the future is actually a competition of algorithms against algorithms, technology against technology. Especially with the explosion of generative AI, cross-border fraud and AI face-swapping have become major disaster areas. This model in Shanghai deeply integrates the technological computing power of major internet companies with the investigative experience of law enforcement agencies. Anti-fraud has never been a battle fought by police officers alone; a 50% reduction is indeed impressive, but that remaining 50% is the hard nut to crack. No matter how technology iterates, the final line of defense is still with us; don’t believe in free lunches falling from the sky.

Recently, the event of drone spraying pesticides during the rapeseed flower period causing a large number of bee deaths suggests that all heroes should proceed with caution, as it involves the future trends of important futures market targets such as rapeseed oil and oilseed meal. Some futures market investigators I know are currently following up on the investigation, and so on.
It’s quite awkward for Chuanzi to find allies for protection; it’s not that I don’t want to come, it’s just that I can’t make it due to running out of fuel. Should I just walk over? For world peace, look at Japan; you see, even Japan has refused [shrug]
Now quite a few countries are urging Japan to clear mines in the Middle East, feeling that only Japan's traditional skill in mine clearance can save the United States. This skill originated after Japan's surrender in World War II when the Americans scattered thousands of sea mines at Japan's doorstep. In order to survive, Japan honed the world's best mine clearance technology. Why are countries, especially the United States, fixated on Japan? Why is Japan so frightened about the 3.19 US-Japan meeting? Discussions have already started domestically about whether going to the Strait of Hormuz for mine clearance would offend Iran. Can the US clear mines? Yes. But the current US aircraft carrier strike groups are meant to deter great powers; they are expensive blunt instruments. It becomes a resource mismatch to have stealth fighters worth hundreds of millions of dollars monitoring rusty iron lumps in the sea that cost a few thousand dollars each. More importantly, if the US military personally goes to clear mines and their mine-clearing vessel is sunk, no matter how strong AI is, it cannot be restored, which would impact the medium term. On the other hand, if Japan's mine-clearing vessels go, they appear more like professional cleaners in the international perspective, with lower political risks and the costs borne by Japan. This is economically referred to as the internalization of negative externalities; whoever lacks oil does the work. Over 90% of Japan's oil relies on the Middle East, so if you don't pay, who will? They specialize in this work. So the question arises: what if Japan's mine-clearing vessel is busy clearing mines and suddenly a rocket fired by the Houthis or someone else comes flying in and blows up the Japanese ship? According to Japan's current "Peace Constitution" and "Self-Defense Forces Law", this could cause a huge uproar in the Japanese Diet. If they retaliate, is it "exercising collective self-defense" or "military provocation"? If they endure it, the domestic public's dissatisfaction could drown the Ministry of Defense. But for the great powers urging Japan to go, this could actually be a surprise. If Japan's ship gets attacked, this would be the best excuse to allow Japan to break through its defensive posture and completely transform the Self-Defense Forces into a regular army. At that point, Japan would not just be clearing mines; they would be collecting protection fees. For the United States, this would also be a litmus test to see how much combat power can be exerted under real combat pressure, while also binding Japan more tightly to their war machine. For the other two great powers, if you have become a regular military, it clearly violates the post-war order, allowing them to strike with impunity. Mines in the Middle East are essentially an additional tax on shipping lanes; as long as the mines are there, insurance rates skyrocket, and oil prices fluctuate. Japan's mine clearance is essentially providing a public good to the global trade system. Everyone praises Japan's mine-clearing expertise, essentially wanting Japan to act as that free security guard. Japan understands this logic; although it feels anxious, it has its own little calculations. Through mine clearance as a non-war military action, it tests the bottom line of the international community little by little. Today it's mine clearance; tomorrow can it be anti-submarine operations? The day after tomorrow, can it be escort missions? But for Iran, this is theft; you're stealing mines from their waters, isn't that being a thief? Japan is also stuck with over 40 VLCCs in the northwest of Hormuz. Many core components and sensors used on Japan's mine-clearing vessels are actually bought from the United States. Japan spends money on equipment, sends personnel, pays oil costs, and runs a long way, only to protect everyone’s oil routes, while also having to bear the risk of getting hit by rockets. Such a foolish contribution is certainly something all countries want to praise, almost wishing to elevate Japan to the status of a little sprite guarding world peace. Everyone secretly thinks of their own interests; the US, Europe, India, and Australia are urging it vigorously, "With great power comes great responsibility, go ahead!"
This article is specifically written for those die-hard fans and followers who have asked me questions in fan groups and private messages. Recently, gold prices have fluctuated greatly, and many have been asking questions. I have compiled these ramblings and concerns into this lengthy piece, discussing four questions simply from my superficial understanding (the content of this article does not constitute specific variety recommendations, only a summary of risk tips and pitfalls I have encountered): 1. Why do most gold jewelry items not have investment value? 2. What are the pitfalls of gold ETF regular investments and how to execute them? 3. What is the wholesale mechanism of Shui Bei gold? 4. How do mainstream foreign institutions view the gold price trend in 2026? 1. Why do most gold jewelry items not have investment value? When we enter a department store and see those shiny gold necklaces and bracelets in the display case, we get excited and think buying them is a form of financial management. In fact, there are many categories of gold jewelry. Simply put, there is regular pure gold, 3D/5D hard gold, ancient method gold, and 18K/22K gold. If you want to invest, what you should value is the metal itself; however, what the seller is selling you is craftsmanship. Why is there no value? To put it bluntly, it’s because the premium is too high. If you buy an ancient method bracelet, and the gold price is 600 yuan/gram, the seller might sell it to you for 750 yuan or even higher. What is that extra 150 yuan? It’s brand premium, store rent, and expensive labor costs. When you walk out of the gold store wanting to liquidate and recover your money, the buyer only recognizes the weight of the gold, and that 150 yuan in labor costs instantly disappears. Especially for those hard gold jewelry items made in bulk, they are light in weight but large in volume, making the unit price shockingly high, which leads to losses that hurt when repurchased. Only the simplest plain gold rings or gold bars, with extremely low labor costs, can barely be considered as retaining value. Also, when traveling in tourist areas, be cautious about buying gold impulsively. Many stores in tourist areas are one-time businesses, and they are most likely to sell tungsten jewelry. Here’s a hard fact: the density of gold is very close to that of tungsten. This tiny difference cannot be detected just by handling it or weighing it on a regular scale. The methods of fraud have also been upgraded; previously, it was gold wrapped outside with lead inside, and now it’s gold wrapped around tungsten or mixed with iridium. Some even have hollow jewelry filled with weighted sand. Some unscrupulous merchants exploit loopholes in X-ray fluorescence spectrometers, only plating a thick layer of pure gold on the surface of the jewelry, making it undetectable by the instrument. If you buy in tourist areas, not only can the premium double, but if you buy counterfeit goods, you may not even find anyone to defend your rights. 2. What are the pitfalls of gold ETF regular investments? Many people turn to gold ETFs after finding physical gold cumbersome to hold. Its advantages are obvious: it has a low threshold; you can buy it for just a few dozen yuan without worrying about being robbed at home, and there is no large buying and selling spread like physical gold. But when to enter the market? Don’t just look at the current soaring gold prices and go all in. Gold is most afraid of missing the boat and also afraid of picking up the wrong deal. When entering the market, it is recommended to choose a time when macroeconomic benefits are fully realized and gold prices have adjusted by about 5%-8%, which is commonly referred to as a reverse pyramid accumulation. This is a routine operation that I did not invent. But the risk that must be noted is actually the redemption period. Many people think that with a click on the phone, ETF money will come back, but you need to be clear about the T+N in the contract. Some gold fund products, although trading is flexible, may take 2 to 4 business days (or even longer, have you ever seen T+7?) to receive funds after you click redeem. There is a huge hidden cost in this. If you urgently need money or the market suddenly crashes and you want to stop losses, during these few days, you can only watch the net value drop without any way to intervene. By the time you get your money, it may no longer be the amount you saw. Additionally, some products have redemption fee rates; if your holding time is too short, the back-and-forth transaction fees may swallow up most of your hard-earned gains. Understanding the redemption rules is the most important thing before regular investments, bro, keep your eyes open, small print counts too. 3. What is the wholesale mechanism of Shui Bei gold? Last year, the Shui Bei model became popular nationwide, and many people wondered why the gold from Shenzhen Shui Bei could be so much cheaper than in department stores. Shui Bei is actually a primary wholesale market for gold. The mechanism here is very simple: market price (the real-time price from the Shanghai Gold Exchange) + extremely low labor costs. The labor costs in branded gold stores in department stores may charge you 80 to 150 yuan per gram, while the labor cost for plain gold in Shui Bei may only be 10 to 30 yuan, or even lower. Why can it be cheaper? Because there is no brand premium here. Some big gold brands, in addition to the gold price, also have to bear the costs of celebrity endorsements, department store commissions, and extensive advertising expenses. Shops in Shui Bei are like vegetable markets, focusing on volume. A stall may have daily transactions worth tens of millions, and they do not need to make high profits on single items; as long as the turnover is fast, even if they only make 2 yuan per gram, it accumulates to a huge amount. But be aware that there are now also chaotic phenomena in Shui Bei. In January this year, many gold price pre-sale platforms exploded, involving amounts as high as 10 billion. Some merchants set up shadow banks, asking you to pay a deposit to lock in prices, only to find that when gold prices soar, they cannot fulfill the promise and run away directly. Buying physical gold in Shui Bei and walking away with the goods is fine; just avoid those so-called gold wealth management products, they are too ridiculous. 4. How do mainstream foreign institutions view the gold price trend in 2026? Finally, for friends who want to hold long-term, here’s an update on the voices of international major banks for reference. Goldman Sachs raised its target price for the end of 2026 to 5,400 dollars/ounce in its latest report at the beginning of March 2026. Their reasoning is due to the continuously rising global debt levels, and private investors are beginning to diversify their asset allocations alongside central banks. UBS had a very aggressive view at the end of January 2026, predicting that gold prices would remain around 6,200 dollars/ounce in the first three quarters of 2026, although they might slightly drop to 5,900 after the mid-term elections in the United States, but overall still optimistic. J.P. Morgan set a year-end benchmark target price of 6,300 dollars/ounce in their February outlook. They specifically mentioned that global central banks are expected to buy about 800 tons of gold in 2026 (which I feel is just hearsay, as they wanted to buy silver last year), which is a solid foundation to support gold prices from falling. Although the predictions of these major banks may not be 100% accurate, they represent the flow of the smartest money globally, giving everyone a baseline to avoid getting dizzy from short-term fluctuations. Just use it as a reference.
A few days ago, Dongche D aired a show about car racing at the Nürburgring, called Dongche Performance Field, featuring three performance beasts: the Porsche 911 GT3 RS, Ferrari 296 GTB, and Xiaomi SU7 Ultra, all racing fiercely. What would happen if these three beasts raced without any competition? Today, a clean lap video without competition was released, finally revealing the truth. Moreover, the professionalism of this interpretation—watching a good video is worth ten years of study!
Waiting for Xiaomi's stock price to gradually enter the main upward trend, this may be one of the most important strategic choices for Xiaomi this year, go for it, Xiaomi
Just finished watching Northeast Police Story 3, I love Xie Miao! Actors like Shi Xiaolong, Wu Jing, An Zhijie, and Wang Baoqiang are considered rare resources. Such actors are also scarce abroad. Action sports training is not something that can be achieved overnight; they have endured too much hardship and offense. They are real men.
Just came out of the cinema, still savoring the last duel in 'The Courier: Wind Rises in the Desert' during that major sandstorm. On one side is the wild hardcore essence of Xu Xianzhe's original work, and on the other side is the standard commercial action blockbuster configuration with Wu Jing and Yuen Woo-ping. After watching it, I felt it was quite solid. The fight scenes were very exciting, after all, it was Yuen Woo-ping. This film did not drop the ball in action design; it can even be said to be a pinnacle of domestic martial arts films in recent years. Today's martial arts films are either filled with cheap special effects or soft, routine setups; after a while, they really become unappetizing. But 'The Courier' features real combat, that kind of visceral impact of punches and blades on the big screen is quite striking. Especially the opening scene in Chisha Town, the three-way melee between the knife horse, the two-headed snake, and Chang Guiren was so fast-paced that I dared not blink. Yuen Woo-ping is very clever; he turned the wind, fire, and sand in the desert into part of the weapons. There’s a scene where the knife horse and another character clash blades in the fire, and the sparks from the blade scraping against the wooden beams, combined with that muffled sound of impact, really made me feel like that blow could shatter bones. This hard style is very Zhang Che, which I like; it's truly been a long time. Wu Jing's portrayal of the knife horse involves the biggest point of divergence between the original work fans and the movie fans. If you were expecting the original character who has a face full of stubble, deep eyes, and a sense of disheveled ruggedness, you might be a bit disappointed. Wu Jing's knife horse still carries that familiar heroic aura of a war wolf. He is too upright; even while crawling through the desert, that soldier king temperament cannot be hidden. The knife horse in the movie resembles a special forces soldier who is forced to return after retiring to a pastoral life, rather than the downtrodden bounty hunter from the comics who wanders on the edge of black and white for survival. This may be Wu Jing's personal style; he has turned himself into a strong symbol. As long as he is on screen, you know this character will definitely win in the end, and win heroically. However, the biggest surprise of this film surprisingly does not lie with Wu Jing but with the character A Yu Ya played by Chen Lijun, whom I have been following for a long time. I heard she was assigned to fill in at the last minute, and I was worried that an opera singer transitioning to a hardcore martial arts film would feel out of place. The result was completely opposite; her gaze when pulling back the arrow was simply stunning. That wildness, resilience, and a touch of fragile beauty brought the character of a desert tribe leader's daughter to life. Perhaps due to her twenty years of opera experience, her posture is very beautiful; her fighting style is not the brute force of flailing, but a kind of strong rhythm. I heard she personally trained for the circus scenes, showing a commitment that is indeed rare in today’s entertainment industry. Also, Li Lianjie’s portrayal of Chang Guiren, though older and with a rounder face, still carries that master-level aura; his every gesture exudes a harsh and domineering presence, which indeed added a lot of energy in the first half. However, as a half-hearted fan of the original work, I must say the literary aspects of this film do have some flaws. The script is clearly subjected to extensive commercial trimming. The original's intricate court politics and the heavy feeling of historical forces crushing all lives were simplified into a relatively straightforward story of escorting a cargo and seeking revenge. To fit the family-friendly atmosphere of the Spring Festival release, the film added quite a few forced comedic moments, making some transitions particularly abrupt. For example, the character Zhi Shilang, who was so transparent and mysterious in the original, sometimes appears in the film as a goofy character meant to lighten the mood. Xie Tingfeng's portrayal of Di Ting turned the originally complex religious beliefs and psychological obsessions into a more easily understandable brotherhood and military honor. I understand this change was made to lower the viewing threshold, making it understandable for ordinary audiences who haven't read the comics, but for those seeking depth, it indeed feels a bit thin. If you view it purely as a martial arts action commercial film, it is worth the ticket price. It is the kind of film that can elevate your adrenaline in the cinema, leaving you feeling great after watching. But after the excitement, there isn’t much left; that sense of fate's helplessness and the era's melancholy, which permeated the original text, is overshadowed by the brilliance of the action scenes. However, the action scenes are indeed beautiful; the last time I saw something this good was 'Chasing the Wind and Capturing Shadows', and before that, it was 'The Kowloon Walled City'. The current martial arts market is indeed cold; Wu Jing stands out to make such a standard heavy industrial martial arts film at this time, regardless of the reviews, this courage deserves recognition. If this film’s box office isn't ideal, it may truly be hard to see such a scale of hardcore martial arts again in the future. I would give this movie a score of over nine, deducting the remaining point for the mediocre script and character deviations. Overall, I still recommend watching it!!!
