"After I die, please stand and bury me, because I spent my whole life kneeling." This is a famous proverb of gypsies. I can't treat gypsies.

Gypsies have no permanent residence. They make a living by divining, taming animals, begging, performing or being sheltered by the government. The key is that they have long been discriminated against politically and socially. I think this is probably the main reason why they live on their knees all their lives. If you want to know more about gypsies, Baidu Encyclopedia has it. That's where I read it.
