What is the best and most promising major in law?

Financial accounting suggests that you choose accounting, because you can engage in finance after learning accounting, but it is difficult to engage in accounting alone after learning finance, and it is difficult to learn and understand tax law without knowing accounting principles. After becoming a corporate lawyer or something else, accounting knowledge will have a lot of room for development.

If you are interested in economics, you can learn it, both macroscopically and microscopically, but you have little advantage in employment because the general trend has basically passed.

International trade majors have higher requirements for English and mathematics, while law majors do not study mathematics, so it is more difficult to learn international trade. But if you want to develop into international commercial law, learning English is good for you. You can also learn international trade if you engage in maritime law or something.
