Legal affairs (lawyer direction) requires that you can get employment as long as you pass the national judicial examination.
Legal affairs (the direction of financial legal affairs) is related to mathematics. If you are not good at math, it will be difficult to find a job. Finance must be sensitive to numbers. If you only know the law, your employment prospects will be bleak.
If you are double-excellent (have passed the national judicial examination, have a certificate in finance, and be better at math if you are sensitive to numbers), the employment prospects in finance and law are very good.
