I suggest you take the postgraduate entrance examination for preventive veterinary medicine in Harbin Veterinary Institute of Chinese Academy of Agricultural Sciences, which is the best veterinary institute in China and internationally renowned. If you want to study in Shanghai, I recommend Shanghai Veterinary Research Institute of Chinese Academy of Agricultural Sciences and Shanghai Academy of Life Sciences (the national leader in life sciences). Personally, I feel that these institutes are better than the life sciences of Shanghai Jiaotong University, and the treatment of the institutes is also better than that of universities. However, Shanghai Academy of Life Sciences belongs to Chinese Academy of Sciences. There are many applicants and the competition is fierce.
