If you want to run a company or a self-employed, you can go through the formalities: 1. You need to prepare a copy of the store's real estate license, (if renting a house, you need a rental agreement) 2 copies of your ID card and 5 one-inch photos. Go to the local industrial and commercial department to apply for business license and organization code certificate first. 2. Submit an application for a health permit to the health supervision department. 3. Go to the tax office for tax registration. In addition, it is estimated that it will take about 2 months for the store staff to have a health certificate, and the cost is less than 1000.
