The regulations don't allow it, but Zhejiang University of Technology is really lax in checking beds. Buy yourself an induction cooker or something. Keep a low profile and don't be found. If you are in Zhao Hui campus, don't buy too much power. Some dormitories will trip if they are not good. If you use an alcohol stove or something, be careful not to catch fire. Try not to get lampblack. It is still possible to get a hot pot when steaming and cooking in winter.
