Help: A long-term visa for the French to go to China.

How many kinds of long-term visas are available in China? If it is a reunion Q visa, it is generally valid for one year. When you arrive in China, you have to go to China to change your visa. If it is a business visa, the validity period is generally one year, and you can apply for a multiple-entry visa with a validity period of five years at the longest, but you need a lot of materials from domestic companies. If it is a work visa, the validity period is basically 1 year, and the types of materials required are different. Mainly depends on whether he will have income in China. If he has income, he must apply for a work visa, which requires the company to provide a lot of materials.
