Among them, the best should be civil law and commercial law, because the academic strength is mainly the contribution of academic leaders and teams, while Lengchuan (Dean of Law School of Guizhou University, member of Party Committee, professor, doctor of law, doctoral tutor (Macau University of Science and Technology), expert of special allowance of provincial government) has outstanding research content, and civil law and commercial law are widely used. I suggest you take a civil law class if you take the postgraduate entrance examination. I wish you success in your studies.
