Chinese hierarchy is so insane that that each citizen has a registration called Hukou - this ties them permanently to the place they're born in.
It is said that moving to a better city is almost as difficult as moving to another country.
Unreal privilege for urban folks.
This is the reality of communism in China.
Ancient China use to have a caste system. "Shi" people were at the top. "Shang" people and "Jianmin" people were at the bottom.
In 1958, the Hukou system permanently classified Chinese citizens at birth based on their ancestral region and family origin.
Urban or Upper Class Hukou: Holders of urban household were put in this category. They enjoy better social welfare, superior healthcare, higher pensions, and better public schooling for their children. Most of the upper class "Shi" people belong to this category.
Rural or Lower Class Hukou: Rural residents and migrants were put in this category. They face systemic barriers their whole life. They have limited access to urban social safety nets, making it difficult to buy property or legally settle in major cities without substantial bureaucratic hurdles. Most for the lower class "shang" and "jianmin"" people belong to this category.
