Based on past experience
After the night plunge
Around 6 o'clock, a small number of Chinese people woke up, bringing a small amount of bottom-buying funds, and the market stabilized and stopped falling.
Around 7:30, most Chinese people woke up, bringing most of the bargain hunting funds, and the market rebounded.
Around 10:30, the last Chinese people woke up, and the market began to rebound at an accelerated pace.
Around 2 o'clock in the afternoon, the bottom hunting funds were exhausted, some ultra-short-term profits were taken, and the market continued to fall.
