I recommend listening to Zhang Xiang's civil law. As far as fame is concerned, Duan Bo, Zhong Xiuyong and Li Jianwei are all famous. However, judging from the understandability of the course and its help to the judicial examination, Zhang Xiang has a relatively strong foundation. It's just that Zhang Xiang doesn't seem to give many lectures in training institutions, and even fewer people may know. Therefore, Zhang Xiang's civil law is recommended from a practical and effective point of view.
