First of all, I suggest you study jurisprudence, master basic principles and concepts, and cultivate legal thinking. You can refer to some law school textbooks.

Secondly, we can learn some relatively simple laws. Such as labor law, contract law, etc. And then study daily life, which is more applicable to property law, marriage law and so on. The civil code is more comprehensive. You can buy one in the bookstore.

Third, I personally think that criminal law, private international law and international economic law are more difficult. If you don't know them, you can watch teaching videos online.

Fourth, if you have the conditions, you can go to a nearby university or join their law study and research group. You can communicate with them and ask them more questions at ordinary times, so that you can understand them more easily.

The above is just my personal opinion, for reference only.
