The so-called "ancient saying" that people cannot help themselves in the arena turned out to be "Gu Long's words", and the dissemination of martial arts novels and various forms has made this saying even more widespread. The signature in the picture below is a splicing of calligraphy from the writer Gu Long.
One is the original calligraphy text: When people are in the rivers and lakes, they can’t help themselves, they fight for every inch of their lives, and they forget about life and death - Gu Long
The other is the only one in the "Jianghu Man" series as Gu Long In "The Sword of the Third Young Master", Yan Shisan made a similar statement, which may be the prototype of this sentence.
First, Gu Long created such a famous saying in "Midnight Orchid" in "The Legend of Chu Liuxiang":
——People in the world cannot help themselves, and love and hatred are difficult to control. Endless grievances.
If you are tired of this life, the only option is to "die".
It’s a pity that some people can’t even die.
