For those who are thinking about going to China and study LLM for one year. I strongly recommend two law shools which are both located in Beijing:
1.Peking (Beijing) University Law School: The Master of Laws(LL.M.) Program in Chinese Law
2.Tsinghua University, School of Law
By the way, here is a article written by Donald Clarke, a professor from George Washington University Law School: Chinese LLMs for Foreigners
The article collects different people's views about studying LLM in China (including lawyer, academic and students).
