What is the essence of Mencius’ explanation of a true man?

The most famous passage in Mencius’s famous sayings about “a true man”: Riches and honors cannot be lascivious, poverty and lowliness cannot be moved, and force cannot bend.

It means: splendor and wealth cannot disturb their aspirations, poverty and humble circumstances cannot change their ambitions, and the threat of power and violence cannot make them succumb.

Mencius’ so-called masculinity has a specific meaning, and it cannot be understood as male chauvinism according to the current secular meaning. The "real man" mentioned by Mencius has nothing to do with physical condition, and does not refer to a person who is "eight feet long". Mencius' "real man" has nothing to do with gender, it does not refer to men, it has nothing to do with power, wealth, the ability to speak well, has nothing to do with erudition, or even brilliance and strategy.
