Well, this person looks at people normally. One month in 300 yuan is enough for girls to eat, but it is impossible to buy snacks and clothes. If you don't buy expensive clothes, five or six hundred yuan a month is enough. For boys, eating doesn't cost more than 400 yuan, but not if you have a girlfriend. There are also boys who want to get together for dinner and an activity, but 700 yuan should have more than enough money every month, excluding extravagance and waste.
