Catfish offspring is a kind of network language, which is often used to describe the descendants or descendants of some people, especially those who have similar personality or behavior habits with themselves. The origin of this word can be traced back to a fable: it is said that a catfish swam across a shoal, was besieged by a group of small fish, and was cornered. Just then, a wise man passed by and saw the plight of catfish. He said to the catfish, "Your descendants will become the overlord of the sea." The catfish was very happy and swam away safely. However, the wise man's words did not come true. Later, the overlord of this sea area was not the descendant of catfish, but other fish. This fable tells us that sometimes we should not rely too much on future generations, but rely on our own efforts to create a better future. Therefore, the word "catfish offspring" has become a kind of satire and ridicule, which is used to describe those who rely too much on their offspring and lack the spirit of self-struggle.
