There is an old saying: "Thirty years in Hedong, thirty years in Hexi." The original meaning is: The Yellow River has a high riverbed, which is heavily silted and often flooded in ancient times, so the Yellow River is often diverted. After every change of route, a village used to be on the west bank of the river, and later it moved to the east bank. Therefore, it is called "thirty years in Hedong, thirty years in Hexi". With the change of social rhythm, it has long been "three years in Hedong, three years in Hexi".

The phrase "three years in Hedong, three years in Hexi" is often used by people in life to describe the impermanence of the world and to lament the changes of life. There are countless examples of "three years in Hedong, three years in Hexi". Some people made a fortune by WeChat business, some people realized financial freedom by live broadcast, and some people made a lot of money by self-media.
