Where is Silicon Valley in the AI era? Huawei Ascend’s chief scientist answers: Not in California—it might be in Wudaokou.
At the end of a five-hour interview, this part made me sit up straight.
His reasoning was especially specific, not just a matter of sentiment:
His own child is studying in the third grade at Wudaokou, and he often goes there to take part in exchanges.
Just find any restaurant or café to sit down—at the table next to you, two people are arguing fiercely:
Why did that loss run off course yesterday? How should reinforcement learning be done better?
His logic for what makes an innovation center is only one rule: wherever the atmosphere and the people are, that’s the center.
So why not Silicon Valley?
He didn’t say Silicon Valley is no good. He gave a more counterintuitive reason:
It’s not that Silicon Valley no longer has the talent-gravity—it’s that these companies themselves have a desire to monopolize, which limits mobility.
Big-company employees wouldn’t discuss the latest reinforcement learning techniques with Stanford undergrads—that’s a confidential competitive advantage.
And China is currently furthest from monopoly, with a talent supply that’s crushing-level. He said that 70% of the world’s top algorithm talent is Chinese, and a Berkeley professor is still teaching the distributive law of multiplication—so the gap is huge.
He also predicted something that’s happening right now:
In these three to five years, we’re in a period where the stars are shining brightly, where a hundred flowers bloom, and where exchanges of ideas are extremely active.
The window is only these few years.
After the whole five-hour interview, I still remember these:
• He said Moore’s Law should be measured in “how many atoms.” Economic milestones like 16/7nm have already stalled, and only energy efficiency is still profiting • Electricity costs for China’s data centers are one quarter of those in the US; the real gap between China and the US chips lies in energy consumption • The benchmark for whether you’ve survived a desperate situation: people start criticizing you • A closing line: when the reporter asked what the most crucial judgment is right now, he only said three words: Betting on China
At 14, he entered Tsinghua’s talent program. In 1996 he went to the US with $1,000. In 2008 his wife pulled him back to China. In 2016 he joined Huawei HiSilicon—he said himself that at the time he “completely didn’t believe China had this capability.”
A decade later, Ascend runs on DeepSeek.
That entire process—an individual’s understanding being slapped by reality and rebuilt again—was all in those five hours.
The biggest magic in Sun Yuchen’s little essay isn’t the $50 million. It’s the bunch of people in the comments who “manage his mindset.” An eyebrow pencil set costing 79 yuan wants to drive the streamer off the platform, while a bride price of 350 million yuan “isn’t anything.” His own account balance is four digits, yet his valuation of someone else’s marriage promise is in the hundreds of millions. Has Xiaohongshu’s sense of deserving inflated to this extent?
The core of this “bookkeeping” set from the Sweet Potato Girl is the “proportion method”: The money you spend on me, as a proportion of your total assets—that’s what counts as sincerity. Is that right? By this logic, if Musk buys you a 30,000-yuan bag, it’s zero cost—so that means he doesn’t love you.
The proportion method only works when it’s used to calculate someone else’s wallet unilaterally. When it’s your turn to split the bill, you can’t squeeze a cent out. Double standards aren’t scary. What’s scary is being so self-righteous about the double standards—and even turning them into a whole methodology.
Most ironic of all: the ones truly trapped by this “sense of deserving” are precisely the girls who believe they deserve it. Quote a price based on fantasy, and the market responds with auctions that get no bids. Value things based on daydreams, and you miss every real match. This is the biggest situation in China right now: demanding prices are wildly misjudging reality.
The platform sells a “sense of deserving” as traffic. And the influencers sell it as lessons. In the end, the one who pays is the fool who still believes.
That high-upvoted comment on Xiaohongshu cursing “Sun Ge” for being stingy got 100,000 likes. And everyone who liked it is fantasizing that they’ve got a diamond-studded—well, you know what.
If the 30 million betrothal gift isn’t refunded, what should this charge be considered as? 1. Breakup fee 2. Money for paying for prostitutes 3. Compensation for lost youth 4. Other
Oh my God, that’s terrifying. The power of the landslide is 10 times greater than a magnitude 10 earthquake. In an instant, everyone was gone—absolutely horrific!

2026 Beijing Robot Sports Games, hosted the world’s first official human-robot table tennis match.
In matches involving low-pressure balls, robots can basically handle it. For balls with slightly higher pressure, the robot technology still needs improvement.
This was done entirely autonomously by the robot, with absolutely no human intervention.
It’s expected that within 1 year, robot tennis sparring practice will become mature. Within 3 years—can robots defeat the strongest human players?
After comparing the data between the Zhuque-3 and the Falcon 9, Zhuque-3 is definitely not the “China version of Falcon 9.”
First, the conclusion: on fuel, Zhuque wins in its generation; on engineering, it’s behind by a decade.
Let’s break it down point by point:
• Zhuque uses liquid oxygen and methane, while Falcon 9 uses RP-1 kerosene • Methane is cheaper, doesn’t clog with carbon buildup as much, and its engine reuse cost is lower • After kerosene burns, it leaves a layer of carbon, so before reusing, the engine must be cleaned
On the fuel front, Zhuque is following the Starship route—newer than Falcon 9’s next generation.
• Zhuque’s rocket body is stainless steel; Falcon 9 is aluminum-lithium alloy • Stainless steel is cheaper and heat-resistant, but heavier • So Zhuque’s 4.5-meter diameter and 660 tons make it about a size larger than Falcon 9 • Improved LEO payload: 21.3 tons for Zhuque versus 22.8 tons for Falcon 9
Use a bigger rocket to carry the same payload.
On materials, this round is basically trading weight for cost.
But the engineering ledger is ugly:
• Falcon 9: first flight in 2010, first recovery in 2015, and to date 676+ successful flights • Zhuque-3: first flight in 2025, only succeeded at its first recovery yesterday • In 2023, Falcon 9 flew 91 launches, with only 4 using a new “core” grade • Zhuque-3 has flown a total of just 2 times
The maturity gap is an entire order of magnitude.
Most stinging is this line: fuel-generation advantages are paper advantages; launch count is the real cost evidence.
Falcon 9 has already turned “reuse saves money” into everyday reality. Zhuque only just entered the test arena yesterday.
Next, we’ll focus on just one thing: for the same first stage, when it comes to re-flying.
This timeline comparison has too much information.
Falcon 9: first flight in 2010, first successful recovery in 2015.
That’s a gap of 5 and a half years.
Jiefang 3: first flight in December 2025, successful recovery in August 2026.
That’s a gap of more than 8 months.
On the same route, SpaceX took five and a half years, while Blue Arrow took eight months.
Yesterday morning, Jiefang 3 Y2 took off at 07:35, and at 07:41 the first stage landed steadily on the Minqin range.
In 6 minutes: orbit insertion + landing recovery—everything went perfectly.
China’s first rocket that can return itself after reaching orbit.
Why is it “the first”? Because this closed-loop works:
• The second stage really sends the Honghu 03 satellite into orbit • The first stage follows the planned trajectory and returns to the land landing site • Both things happen simultaneously in the same flight
Engines and the rocket body are the most expensive parts of a rocket—reusability is basically picking up money.
But don’t rush to hype it yet.
Falcon 9 has achieved success for 676+ flights, while Jiefang 3 has only flown twice.
Catching up in 8 months is matching the first time—not achieving the 676th flight.
Next, an even more important thing: for the same first stage, when will it fly again.
Only when it’s reused does the cost accounting really hold up.
