I go to school in Huai 'an, grade three this year, but I will graduate soon. There are quite a few mobile package services there. You can choose what you need to open, which can reduce considerable expenses. For example, my average is about 60, and when I don't use it much, I can pass 30. Seriously, the food there is not cheap, don't underestimate it, and there are quite a lot of snacks (then you can try the normal street there, and of course the hygiene is good). If you are a girl, to be honest, you still spend a lot of money. Everything just needs a sip of water outside. There are Huitong, Women's Street and Golden Eagle (from low to high). Girls like shopping and will buy blindly, but I hope you will go home and buy expensive things, unless you like it very much, it will go far beyond the plan. The weather there is dry. I can't say that I haven't been anywhere. Combined with myself, my living expenses are generally around 700~800. Of course, there are also big items that need to be requested at another time. I hope you are satisfied.
