I want to start a lunch nursery department. What procedures do I need to go through?

you should apply for a business license at the industrial and commercial department.

materials required for handling the business license of self-employed households: application for registration of establishment of individual industrial and commercial households, copy of the applicant's identity certificate, certificate of use of business premises, notice of pre-approval of shop name, power of attorney and relevant pre-documents.

Procedures for handling the business license of individual businesses:

Receiving the Application Form for Establishment Registration of Individual Industrial and Commercial Households → Submitting documents and applying for establishment registration → Paying the registration fee and obtaining the business license.

undertaking department: registration department processing time: 15 working days.

of course, if you are bold, you can do it without listing and formalities. Generally nobody cares.
