I believe you should understand the difference between these two majors. However, I still want to remind you, don't really think that the master of law is doing academic work, and the master of law is doing practical work. In fact, a specialized judicial system like the Public Prosecution Law likes to recruit a master of law, and the next best thing is to consider a master of law, whether it is a master of law (illegal study) or a master of law (law). You can ask your friends in the public security system about this. LLM's way out is not just a lawyer. In fact, there are fewer lawyers after graduation, and most of them have entered the public security law or been admitted to civil servants in other government departments.
I suggest you consider a master of law, choose the direction of criminal procedure law, focus on theoretical study first, and start internship from the second year (you can go to the public security inspection law for internship) to do more practical work. Master of Law has no direction basically, and the courses offered after entering school are similar to those of undergraduate law, that is, some basic legal courses can be offered, which can be related to investigation, that is, criminal procedure courses, and the opening time is relatively short.
Recommended schools are: Law School of Renmin University of China (Evidence and Investigation), School of Criminal Justice of China University of Political Science and Law (Criminal Investigation) and Institute of Criminal Science of Beijing Normal University (Criminal Procedure Law). This is the difficulty of the postgraduate entrance examination for master of laws in three schools, and it is also arranged in this way. Among them, 8 people were first examined by the National People's Congress and the Central Committee, and 4 people were first examined by the Institute of Criminal Science of Beijing Normal University. Good luck!
