This stem comes from the hit drama "The Knockout" episode 1 1. Gao Qiqiang's line: "Help me find Lao Mo and tell him that I want to eat fish." A noun belonging to evil forces. Faced with the provocation of the villagers in Mangcun, Gao Qiqiang became angry from embarrassment and prepared to take violent repression to silence the other party. "Lao Mo, I want to eat fish" is like "I'll take you to climb the mountain" in "Hidden Corner". These two sentences have a deeper meaning. Eating fish and climbing mountains means killing people.
Gao Qiqiang used to be a small fishmonger. When he has enough strength, he regards his opponent as a fish. As long as he wants to get rid of that person, he will tell the old man "I want to eat fish" and the old man will do it at once. He is loyal to Gao Qiqiang. If the boss wants to eat fish, he will kill it.
