What does it mean to write all categories on the business license of individual industrial and commercial households?

The business license of individual industrial and commercial households is written in categories, which usually means that the business scope of the business license is wide, covering many industries and fields. The business scope of all categories includes industries such as industry, handicrafts, construction, transportation, commerce, catering, service and repair. These industries and fields are all within the scope of individual industrial and commercial households, as long as they are within the scope permitted by national laws and policies.
