Self-employed businessmen are natural persons or families who are engaged in industrial and commercial business activities within the scope permitted by law and approved for registration in accordance with the law. Individual industrial and commercial households can be individuals or families who engage in industrial and commercial business activities in their personal name or in the name of their families, mainly providing occupations such as production, service and trade. Individual business households operate in a wide range of industries and fields, such as retailing, catering, handicraft production and domestic services. Individual industrial and commercial tenants usually bear the business risks and responsibilities independently and enjoy corresponding business returns. They need to comply with relevant laws and regulations in the course of business, such as tax regulations, labor laws, etc., and also need to bear the corresponding taxes and social responsibilities. Individual industrial and commercial households are characterized by relative flexibility and can make business adjustments according to market demand and individual capabilities, but they also need to face the challenges of competition and market fluctuations.
