Why did Tianqi Film's stock fall to 47.63% on May 9?

In the first three trading days, the adjustment range from high point to low point exceeded 260 points. Today, the market opened higher, up 100 points, a rising K-line combination. Why is this market so unstable? In fact, we have all analyzed the root cause before, that is, the market entered the range of 3000 to 3400. On the one hand, it needs to be adjusted because of the large increase. On the other hand, there are a large number of locking plates in this interval, and violent fluctuations are inevitable. Therefore, on Monday, we emphasized that the callback should be near the 20 th line. Finally, it did stop falling and rebound near the 20 th line yesterday, and today it rushed directly. This is the market rhythm in the bull market, and those that don't adapt will be dumped.
