In my opinion, people who achieve great things are informal. A section is a detail that does not affect the outcome of things. Because it does not affect the result, caring about him can only waste time and energy, which is not conducive to achieving great things.

For example, Liu Bangsan's visit to Cambodia, Wei Zhi's outspoken attitude towards Cambodia, Li Bai's tepid attitude, and Ji Kang's light experience of Ruan Ji are all favorable proofs that successful people are informal. If a person puts his point of view on the details, he can't see the comprehensiveness of the problem, let alone grasp the situation well, or put his limited energy into the most critical link.

Imagine, if Liu Bang is angry, how can there be a situation in which the three countries are divided? Wei Zhi is timid and Li Shimin is small, so there is no rule of chastity; Li didn't have many eternal songs in red tape; Ji Kang's Ruan Ji follows earthly details. How can Guangling San not be mysterious?
