A dormitory around 200 yuan. The dormitory of the university and the campus are together, so the daily transportation cost is not high, basically around 50%. Water and electricity card recharge: there is a difference between college and home. Students need to pay personal utilities, 50 yuan (water) +50 (electricity) = 100 yuan.

Telephone and internet charges: everyone can't live without mobile phones and the internet, so it also needs to be spent. Some students may have parents to pay the bill. 50 yuan (phone bill, campus phone card is cheaper) +30 yuan (Internet access fee) =80 yuan.
