From Which university can I do Master in Environmental science in China?

Hi, Zhejiang University, Tsinghua University and Tongji University may be your choices. They can be considered the toop three ones having the Environment Science major. So you can try to search some information of the three.
As for the scholarship, it changes from university to university and from major to major, so it is a little hard to tell the exact information. I suggest you search the official website of these schools to know more.
