Are there any rules for selling scented paper candles?

You need to go to the industrial and commercial bureau to apply for a business license.

The phrase "projects subject to approval according to law can only be operated after obtaining relevant approval" must be reflected in the business license, because different enterprises have different business scopes and may involve post-licensing matters.

The purpose of this sentence is to remind the business entity that if the business scope involves pre-licensing (post-licensing), it needs to go through relevant procedures before it can operate.
