China has continuously issued new shares in recent years, from more than 3,000 in the past to more than 4,000 stocks now listed.

Because China's stock market is immature and unsound, market makers and institutions often control the market, often cutting off retail investors, and there are ups and downs. They especially like to speculate in new stocks. In addition, the epidemic in recent years has affected the real economy, seriously affecting the stock market. In addition, the stock market has insufficient blood transfusion. Insufficient funds, the overall stock market is like a cake, the cake is only so big, and there are too many people who want to arbitrage money in the stock market. The overall volume is difficult to expand, but shrinks on the contrary.
