Some school dormitories have power cuts (high-power appliances will trip). In this case, most schools help pay the electricity bill, or pay the electricity bill together with the tuition fee when the school starts. One of my classmates is only 300 yuan a year. I think besides eating, the biggest expenses of studying abroad are telephone, internet and electricity. Together, I can give them 200 yuan in a month.
