"Success is also Xiao He, failure is also Xiao He" means: success and failure are both caused by the same person. "Success is due to Xiao He, and failure is due to Xiao He" comes from "Rong Zhai's Continuation of Xiao He's Letter to Han" written by Hong Mai, a writer in the Song Dynasty. The original words are: "The letter is a general, and it is actually Xiao He's recommendation. Now that he is dead, it is out of his words." Conspiracy. Therefore, there is a slang saying, "Success is Xiao He, failure is Xiao He".

"Success is also Xiao He, failure is also Xiao He" originates from the story of Xiao He and Han Xin in history. Success by Xiao He means that Han Xin became a general because of Xiao He's recommendation, and failure by Xiao He means that Han Xin was killed because of Xiao He's plan.

Under Xiao He's recommendation, Han Xin became a general under Liu Bang, the emperor of the Han Dynasty. After Han Xin became a general, he gave full play to his military talents and made great achievements in establishing the Han Dynasty.

But Liu Bang became more and more suspicious of Han Xin, so he asked Empress Lu to get rid of Han Xin. Fearing that he would not believe it, he asked Xiao He to come forward to lure Han Xin. Finally, Xiao He designed to deceive Han Xin. In the palace, he was killed in the bell room of Changle Palace.
