The ability to rule the world means leaning in troubled times.

The phrase "a minister who has the ability to manage the world is a fierce one in troubled times" means: if he is in peace and prosperity, he is a capable minister; If it is in the year of war, it is fierce and dominant.

This sentence, "a capable minister who can rule the world, a lean man in troubled times", is the earliest evaluation of Cao Cao by Xu Shao in Runan.

In his book Seventy Years of Late Qing Dynasty, Mr. Tang Degang said that in modern history, only Li Hongzhang and Zhou Enlai were "capable officials in the world and fierce in troubled times".

In the Tang Dynasty, Zhang Huaiguan named it a "wonderful flower" at the end of Shu.
