The colloquial word "commercial" means "commercial use", which is a kind of profit-making behavior. Uploading a vlog shot by a person to a station similar to a certain sound, a certain hand, is also classified as a commercial act in a strict sense.

in legal practice, the identification of commercial use does not only refer to obtaining financial benefits, because in modern society, the forms of obtaining benefits also include attracting attention and obtaining fans. Although these methods do not directly bring economic income to publishers, they bring the possibility of obtaining economic benefits to publishers.
