I read Li Xiaolai's "The Self-cultivation of Chives" and it answered a question for me at the beginning. Every time the aunts and uncles on the roadside buy stocks, the stock has reached the top. Of course I know, but I can't explain why because the liquidity has dried up. The aunts and uncles are the middle class in society. After they bought the last financial force, there was no new money to enter the market. The increase in stock price was driven by the buyer's trading volume. I'm so stupid. This is all logic that I clearly know.​​​
