There is an old saying, "Thirty years to the east of the river, thirty years to the west of the river." What does this sentence tell us?

Explanation Thirty years ago, Feng Shui was on the east side of the river, but thirty years later it was on the west side of the river. It is a metaphor for the changes in the world, the ups and downs.

Sourced from Chapter 46 of "The Scholars" by Wu Jingzi of the Qing Dynasty: "Mr. Da, 'Thirty years in Hedong, thirty years in Hexi'! Just like thirty years ago, the two of you What an advantage, I have seen it with my own eyes."

Allusion

After the Anshi Rebellion broke out, Guo Ziyi led his troops to conquer the north and south, and made great contributions to quelling the rebellion. Therefore, Emperor Tang Ming betrothed the princess to him. She became Guo Ziyi's daughter-in-law and built him the magnificent Hedong Mansion.

Needless to say, the whole family was happy when a grandson was added to the new house soon. However, Guo Ziyi’s grandson grew up in honey water and was spoiled and spoiled. When he grew up, he was extravagant. After the death of his ancestors, the family gradually declined. , Within a few years, Wan Guan's family property was exhausted, and he had to beg on the streets. One day, he came to Hexi Village and remembered his nanny from more than 30 years ago, so he went to look for her. He asked all around the village, but people said they didn't know. Guosun was very disappointed. It was getting dark, and at this time, he came again. A farmer came up and asked about it, and it turned out that he was the wet nurse's son. They talked and walked, and soon they arrived home. Entering the courtyard and looking around, I saw grain hoards and herds of cattle and horses. Guo Sun asked puzzledly: "The family is so rich, why do you still have to work by yourself?" The master said: "No matter how big the family property is, there will be times when it is all empty. When my mother was still alive, she led us to work hard to start a business, so we got the family property." There is endless fun in being diligent and thrifty!" Guo Sun was very ashamed after hearing this. The master did not forget his old friendship and detained Guo Sun as the accountant, but he knew nothing about accounting. The master couldn't help but sigh: "It's true that Hedong has not enjoyed all the glory and wealth in thirty years, and Hexi has been under the fence for forty years."

From then on. , "Thirty years to the east of Hedong, forty years to the west of Hexi" spread.
