the industrial and commercial department handles the business license.
if you want to apply for a self-employed business license, you can go directly to the local industrial and commercial bureau. You can apply for a self-employed business license as long as you bring a copy of your original ID card, a one-inch bareheaded photo, relevant procedures of the business premises, lease contracts, etc.
if your business involves food, catering, etc. and requires other licenses, you must go to the Food and Drug Administration for the relevant licenses after the name is pre-approved by the Industrial and Commercial Bureau, and then you can go to the Industrial and Commercial Bureau for the individual business license.
