Is a piece of paper thin enough? If you fold a piece of paper in half 27 times, it will be 13 kilometers thick. If you fold it in half 10 times and fold it 37 times, the earth will not be thicker than it. If you fold it 105 times, the entire universe will not be able to accommodate it. If you have 30,000 yuan in capital, you should think about how to triple it in one wave, and then triple it again in the next wave... Then you will have 400,000 or 500,000 yuan;
