Hedong in three thousand years, Hexi in three thousand years, not bullying the young and the poor. From where?

In the past, the Yellow River was not fixed and often changed its course (it happened countless times in history). A place used to be on the east side of the river, but in a few years, due to the diversion of the Yellow River, this place will become on the west side of the river. This sentence is a metaphor for the ups and downs of personnel, which is changeable and sometimes becomes the opposite and unpredictable.

Thirty years in Hedong, thirty years in Hexi, not bullying the young and the poor.

It means: thirty years in Hedong, thirty years in Hexi, the wind and water turn, and things change. Don't bully a young man just because he is poor now.

Synonym: This time is different.
