some questions about America some people will think i am vulgar after read my questions,but i ony want to kown because of my curiosity. so don't laugh at me please. Is America really richer than China so much ?in the movies I saw almost every family has one villa ,no matter how many children they have ,they can offer one big enough room for erevy child.many people has own car,and they change their cars as same as Chinese buy clothes,they don't hesitate.but in China,many plepeo are vexed about purchasing own car and house which is not a villa but in a mansion ,it has been a social hot issue now. I will have no ability to go abroad in the furture,so i can't explore by myself,help me please!who can?t there are mang errors , so… thank you very much!!
