I want to know more about the water and electricity charges of Jinan University, how much water and electricity can be used free of charge every month, and how much is overcharged.

The water and electricity charges are settled every two months, and each person issues 10 kwh of electricity, 10 ton of cold water and 10 ton of hot water every month. If there are four people in a dormitory, the two-month distribution quota is 80 kWh, 80 tons of cold water and 80 tons of hot water. Generally, the hot and cold water will not exceed, but the electricity fee will exceed, which is about 1 yuan per meal, and the electricity fee is 60 cents (Zhuhai).
