It depends on what kind of law, substantive law or procedural law you like or are familiar with.

Procedural law: choose the prescription and jurisdiction of any one of criminal litigation, civil litigation and administrative litigation, and pick one that you are good at, including definition, historical evolution, comparison at home and abroad, current situation and typical cases. . . . . Conclusion and so on

The most important thing is that you think clearly about the logic and branches yourself, and then fill in the content to prove your logic and conclusion.

Substantive law, also roughly the same.

Haha, scrawled. Read it.
