"Those who are not arrogant in victory and do not be discouraged in defeat, who have thunder in their chests and a face as flat as a lake, can worship the general." This sentence comes from "Emperor Zhuang Lie, Volume 1: The Weak Crown Emperor".
The original sentence is "If you win, don't be overjoyed; if you lose, don't panic; if you have thunder in your chest and face as flat as a lake, you can worship the general."
Explanation: If you win, don't I'm so happy; don't be too discouraged if you lose. People who have great ambitions but are ordinary on the surface (cannot see it) can be given a very high official position.

The content of "The First Volume of Emperor Zhuang Lie, the weak crown emperor":
Historically There are emperors who either founded a country, established a great government, expanded the territory, or revived the state. The king of a subjugated country is either tyrannical, stupid, or cowardly. Only Chongzhen, who had absolute control and was also the hardest-working emperor in Chinese history, devoted all his energy to the country, but worked hard to give away the great tomorrow. The reason for this is worth a book.
