Avatar has attracted increasing attention with the spread of the Internet, and has begun to provide various services in recent years. From the viewpoint of the user, it is simple to change the avatar skin and enjoy dressing them up. From the company side, it is important to develop a business model to manage the content. This paper examines the connection between user communication and content, as well as the mechanism of content development by teams of designers.
