There are three main types of financial industry: banking, securities and insurance, which are supervised by CBRC, CSRC and CIRC respectively. In addition, I think lottery tickets and pawn shops should also belong to the financial industry.

The banking, securities and insurance I mentioned are relatively broad categories. For example, the banking industry includes policy banks, commercial banks, credit cooperatives, postal savings, asset management companies, trust and investment companies, finance companies, financial leasing companies and so on, while the securities industry includes stocks, futures, funds and so on, with a wide range.
