Primary industry: agriculture (including planting, forestry, animal husbandry, sideline and fishery)

Secondary industry: industry (including mining, manufacturing, tap water, electricity, steam, hot water and gas) and construction.

Tertiary industry: other industries except the primary and secondary industries. Because the tertiary industry includes many industries and a wide range, it can be divided into two parts according to the actual situation in China. One is the circulation department and the other is the service department. Specifically, it can be divided into four levels:

The first level: the circulation department, including transportation, post and telecommunications, commerce, catering, material supply and marketing and warehousing.

The second level: departments that serve production and life, including finance, insurance, geological survey, real estate, public utilities, residents' services, consulting services and comprehensive technical services, agriculture, forestry, animal husbandry and fishery, water conservancy services and water conservancy, highway and inland waterway maintenance.

The third level: departments that serve to improve the scientific and cultural level and the quality of residents, including education, culture, radio and television, scientific research, health, sports and social welfare.

The fourth level: departments that need to serve the public, including state organs, political party organs, social organizations and special departments such as the army and police.
