Except for special circumstances, the food in the canteen is similar to that outside, and even many dishes are cheaper than outside. It is good that the unit has taken care of some poor students. The disadvantage is that, after all, it is in the school cafeteria, and there are fewer special dishes and the like than outside, so if it is a dinner party or something, it is best to go outside. In terms of price, at the current market price, one month's living expenses in 800 yuan can be enough. You can raise it a little if you want to eat. If the family condition is poor, it can be reduced to around 400 yuan.
