What you are saying should be "He who knows the current affairs is a hero"

Interpretation: It means that only those who can recognize the trend of the times and are smart and capable can be heroes. Only by recognizing the trend of the times can one become an outstanding person.

Source: "Yan Zi Chun Qiu·Hegemony arises due to the times" Yan Zi: "Those who understand the current affairs are heroes, and those who adapt to changes are heroes."

"Three Kingdoms·Shu Zhi·Zhuge Liang Biography" Pei Songzhi Notes quoted from "Xiangyang Ji" written by Xi Chizhi of Jin Dynasty: "Confucian scholars and laymen, those who know the current affairs are heroes. There are crouching dragons and phoenix chicks here."

It is undeniable that "those who know the current affairs are heroes" As a wise saying goes, quilters have always been regarded as suspected of escaping and betraying, but this is not the case. That's because those people don't really understand what it means.

"Current affairs" should refer to the "main theme" or mainstream of world affairs, rather than some "episode" or tributary. He refers to being good at judging the situation (potential) in dealing with people. This is extremely important for a person's success.

Successful people are those who know the current affairs. People who live in a dream are rarely successful. It is precisely because successful people can see through the development trends of world affairs and plan out comprehensive strategies to adapt to the development of world affairs that they can be successful.

I think this is the best explanation of the two words "real (real-time) affairs". And what kind of person can be called a hero? That is, when a certain person is faced with a big situation, he can make an accurate analysis of the current situation and the balance of forces, clarify the interests and conflicts of all parties, and thus put himself on the favorable side. Buriusov once said: If possible, then be ahead of the times; if not, then move forward with the times, but never fall behind the times
