Please explain the detailed meaning of this text message. Please explain each sentence.

The beauty of a gentleman is not the evil of a man. The opposite is true for villains. The phrase comes from "The Analects of Confucius·Yan Yuan" and means: A gentleman usually fulfills other people's good deeds and does not destroy other people's affairs, but a villain is exactly the opposite.

"If you are poor, you can be good for yourself; if you are prosperous, you can help the world." It comes from "Mencius: Doing Your Heart", which means "When you don't have ambitions, you should clean yourself up and cultivate your personal character. When you have ambitions, you can make the world do the same."

Asking you how much sorrow you can have is like a river of spring water flowing eastward. From "Poppy Poppies", this sentence is the title of the whole poem, and it is also a quatrain through the ages and has been widely circulated. Li Yu can only ask and answer his worries. "Spring Water" has some petals, which are tangible and vivid, making the word "sorrow" three-dimensional. The most recent association with "flowing eastward" is "A Hundred Rivers reach the sea from the east to the sea, when will they return to the west?" in "Long Song Xing". But "flowing eastward" has a deeper meaning. The water flowing eastward can be understood as Confucius' "water flowing eastward" "The dead are like this", which can also be attached to the meaning of "tears flowing into the Yangtze River", which can be said to be "a sorrow through the ages".
