Take the exam if you like Sino-German relations law. This direction should have a good prospect and there may be less competition.
Speaking of the future development, I don't think criminal law and criminal prosecution will be too bad, because the brand of China's politics and law is there.
A doctorate, tutor, etc. If you look for information on the "Sea and Yun Fan" forum of China Political Science and Law Network, you will gain something.
Good luck!
