It is compulsory to have a visa in order to enter China, no matter how long you plan to stay there.
If you are staying for less than 3 months, a (tourist) visa L is sufficient. If you are staying for longer than 3 months, you need to request the (business) visa F.
We will assist you during the process and provide you with the necessary documents.
