What is the meaning of the sentence "everyone knows the gentleman"

I believe many people have heard of this poem, "Mochow will have no confidant in the future, and no one in the world will know you." So what does this sentence mean? Let's get to know each other.

1, no one in the world knows you. The original sentence means that no one in the world knows you, which means that no one in the world knows you!

2. This poem comes from one of the two poems "Don't Move Big" written by Gao Shi, a poet in Tang Dynasty. These two poems are the farewell works of Gao Shi and Dongda after a long separation. After a short party, they parted ways.

3. The work outlines the gloomy and cold sad scenery when bidding farewell, showing that the poet was in a difficult situation at that time, but he was not depressed or sinking, which not only showed the poet's reluctant farewell to his friends, but also showed the poet's heroic and open-minded mind.

The meaning of the sentence "Everyone knows the monarch" is so much.
