The conditions are simple. First of all, you have the ability to bear criminal responsibility, and you are over 18 years old. No special requirements. You can write your business scope at will. When registering in the industrial and commercial bureau, anything that is not mainly within the scope of "unregistered" can be used.
The materials that a registered company needs to prepare are: shareholder ID card (and its copy), registered capital (you can find someone to pay for it), office lease contract, and a copy of office property right certificate.
