1, bullying a white beard is better than bullying a poor boy. I would rather look down on an old man who has no money than a poor young man, because the future of young people is limitless.

2, there must be a day when the dragon wears the phoenix. I don't believe I will wear pants. It means: if young people work hard, they will have a successful career sooner or later, so they don't believe that they will always wear pants with holes all their lives.

3, thirty years in Hedong, thirty years in Hexi, not bullying the young and the poor. It means: the wind and water turn, things change, don't bully a young man just because he is poor now. Allusion: In the past, the Yellow River was not fixed and often changed its course. 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.
