If it is a judicial examination, I suggest listening to Mr. John Yang from China University of Political Science and Law. His lecture was lively and interesting, and focused.
Other famous artists include Li He.
Supplement:
There is no doubt that Jiao Hongchang (Professor of Constitutional Law at China University of Political Science and Law, Deputy Director of the Law Department and Director of the Constitutional Teaching and Research Section) and Mr. john young spoke very well.
The authoritative teacher of criminal law is Ruan Qilin (Professor, School of Criminal Justice, China University of Political Science and Law, Supervisor of Master of Criminal Law). I have listened to Ruan Qilin's class, and his theory is very thorough.
Zhang Mingkai (Tsinghua University Law School, Director of china law society).
Chen Yongsheng (Professor of Peking University Law School), I have also listened to Professor Chen Yongsheng's lectures, which are very concentrated and the handouts are very good.
Chen Xingliang (Professor and Doctoral Supervisor of Law School of Renmin University of China) and Mr. Chen Xingliang are criminal law examiners in the current judicial examination. It's a pity that I haven't listened to his class. It should be of high level.
