The first thing you need to know from the north is that there is no heating, and it is wet and cold in winter. Some students in the north said that the temperature here is not low, but it feels much colder than in the north, both indoors and outdoors. But don't bring any heating appliances, because the power shortage here is too serious. It seems to be 600 watts during the day, 200 watts at night or more than 100 watts, not per capita, but the total watts of a dormitory for four people. Don't even think about it People who are afraid of the cold had better bring a quilt thick enough, because the two beds are not very warm when stacked together. I can't remember anything else for the time being.
As for living expenses, it's up to you. Four or five hundred and one months is ok. There is no end to more. But overall, the students in Central South are relatively simple, compared with some other universities. The living expenses of freshmen should be prepared more. The first month may be as much as the next few months.
I'm not sure about bioengineering, because I'm not from Zisheng College. But some of my classmates are bioengineering majors, and I thought about it at the beginning. It's not a very good major in Central South. As far as national employment is concerned, it is not very good either.
