In rice circles, fans are often cut into leeks by their favorite beans. Star brokerage companies use fans' love for their idols to make fans buy products endorsed by consumer idols, or star artists bring goods, make fans pay, squeeze and stimulate fans' consumption, and treat fans as cash machines. After cutting this crop of fans, they will continue to cut leeks after a while.
In addition to stock market terms, leek also means cannon fodder on the internet. When describing a thing that requires a lot of cannon fodder and practitioners, and it is usually meaningless, or the controller can profit from it, it can be used to cut leek.
