the main force began to enter, and then the stock price was raised before the fund-raising was suppressed. Before the daily limit, everyone in the stock was quilted. After several days of continuous overcast decline, all retail investors lost confidence and took a wait-and-see attitude, and some of the quilted ones cut their meat. When retail investors lost confidence and the profit-taking disk was close to zero \CYS value was close to -16, it showed that the stock was oversold (it could rebound at any time), so it was good for the main force to enter.
