"Thirty years east of the river, thirty years west of the river, don't bully the young poor" means: thirty years east of the river, thirty years west of the river, the wind and water turn, and things change, so don't bully the young poor now.

It means: I would rather look down on an old man with no money than a poor young man, because the future of young people is limitless. The white bearded man is an old man with a white head.

the origin of "thirty years in the east of the Yellow River and thirty years in the west of the Yellow River": The Yellow River has been diverted many times in history, and the village originally on the east bank of the Yellow River was changed to the west bank of the Yellow River after many years of diversion.

Don't bully the poor youth, which comes from the 46th chapter of The Scholars written by Wu Jingzi in Qing Dynasty.

"Thirty years east of the river, thirty years west of the river" is a proverb, which means the ups and downs of the world are impermanent. Back to the 46th chapter of The Scholars: "Father Cheng said,' Mr. Da, thirty years east of the river, thirty years west of the river! Just like thirty years ago, how imposing your two houses were! I saw it with my own eyes. " "

and" ten years east, ten years west "may be a variant of it. East and west refer to the north and south banks of the river. Because the Yellow River often changes its course, it is used to describe the ups and downs of personnel.

actually, there is a story about this.

Guo Ziyi's grandson came to Hexi Zhuang begging along the street because he squandered money like soil. He thought of his wet nurse and went to look for it. He asked a lot of people, but people all said that they didn't know. When it was getting dark, a farmer came. When he came forward to ask, he turned out to be the son of his wet nurse. When he went to someone's house, he saw that there were seats for food and horses and cattle. He asked, "Your family is so rich, why do you have to work by yourself?" The son of the wet nurse said, "No matter how big the family property is, it will be empty.

when my mother was alive, she led us to start a business. Diligent housekeeping is fun! " Guo Sun was ashamed after hearing this. The master did not forget the old feelings, so he let Guo Sun take care of the accounts at home, but he knew nothing about the account management. The master could not help sighing: "It's true that Hedong enjoyed endless splendor in thirty years, and Hexi was full of people in forty years."

"Thirty years east of the river, thirty years west of the river" is broadcast here. The so-called "one time for a while".
