Civil and commercial law, miscellaneous and extensive, has learned a lot of laws, but most of them are not very deep (do not need too much legal knowledge), so it is good for employment.
Criminal law and criminal procedure: suitable for civil servant procuratorates and courts in the future. The employment scope is relatively narrow, but it is logical and theoretical.
Economic Law: It's very difficult. If it is a big economic law, you may have to learn some contents of commercial law. Foreign languages are also important, high-end talents.
Others, such as international law, jurisprudence, constitution and legal history, are minor laws, depending on your personal interests.
