Does the studio have to be called "xx xx Studio"? Does the word "studio" have to appear?

Not necessarily, the studio is a self-employed enterprise that has gone through the industrial and commercial registration formalities in the industrial and commercial bureau and obtained a business license. Compared with the company, first, the registered company has the requirement of registered capital, and the registered studio has no requirement of registered capital. Second, the studio can't invoice itself, but the company can invoice itself, which is more convenient than the studio in operation.
