Rank you according to difficulty. Hainan University, Guizhou University, Guangxi University, Yunnan University and Hainan University have a good reputation but are very watery. If you just pursue the difficulty of the exam, recommend Hainan University. If it is a major, I recommend Guizhou University.

Environmental engineering in Guizhou University is still possible. There is a first-class master's degree program in environmental science and engineering (College of Resources and Environmental Engineering), which can win about two national natural science foundation projects for the environment every year, and the teaching staff is good; In addition, the College of Life Sciences and the College of Agriculture are also recruiting graduate students in the field of environment. It is recommended to study in the College of Resources and Environmental Engineering.
