What do you mean, people cut leeks?

The word "cutting leek" has been circulating wildly on the Internet for a long time, and many people don't understand what it means, let alone what it is:

Generally described as large institutional funds: selling stocks leads to a sharp drop in the stock market or individual stock prices, ushering in new opportunities to open positions, and then re-opening positions at a low level. Such a circular belt operation is called cutting leeks.

Generally, retail investors are described as buying stocks, buying a set, cutting a set, cutting a set and buying a set, resulting in heavy losses. Also called leek cutting.
