Washing dishes is to scare off retail investors by falling in the process of the banker's pull-up, so that they can throw out their shares, and the banker can buy them again, or let new retail investors buy them, thus increasing the cost of opening positions for retail investors.

Shocking warehouses is similar to washing dishes, both of which are aimed at scaring off weak-willed retail investors.

A rat warehouse refers to a dealer who buys a lot from himself or his relatives and friends before preparing to raise the stock price, thus earning private profits.

Disturbance is a process in which the dealer sells a large number of orders, resulting in the stock price falling.
