Which is more difficult for Wuhan University’s postgraduate entrance examination, majoring in private international law or majoring in civil and commercial law?

Both are difficult, but relatively speaking, international law and private international law are more competitive. If you want to take the exam, you must study hard. I have a resource book on private international law from Wuhan University here. , "2014 Wuhan University 833 Private International Law and International Law Postgraduate Entrance Examination Review Compilation" should be able to help you, you can check it out on the Luojia Wuhan University Postgraduate Entrance Examination Network
