To be fair.

Countries all over the world divide various industries into three categories: primary industry, secondary industry and tertiary industry. The primary industry refers to industries that provide means of production, including planting, forestry, animal husbandry, aquaculture and other production departments that directly target natural objects. Although some of them are industries, they are not processing industries. For example, the mining industry directly provides minerals but does not process them, so the mining industry belongs to the primary industry. The secondary industry refers to the processing industry that uses basic means of production to process and sell. The tertiary industry, also known as the service industry, refers to other industries other than the primary and secondary industries. The tertiary industry is extensive. Including transportation, communications, commerce, catering, finance and insurance, administration, family services and other intangible production sectors.
