Red herring fallacy? That is, the fallacy of changing the topic is to insert an irrelevant topic into it according to certain skills, and shift the other party's attention and discussion direction to another topic, thus winning the debate.

Origin: Herring is a kind of fish, which is not red at first, but becomes deep red after curing and smoking. It has a strong smell. People put smoked red herring in fox-infested places to test the hunting ability of hounds. Later, people used red herring to express false clues or forged facts to confuse opponents, which first appeared around 1420, and its figurative meaning was not used until 1884.
