The popular experience officer displayed on Douyin avatars is a new feature launched by Douyin to improve the user experience and interactivity. Popular experience officers refer to users who have a certain number of fans on Douyin and actively participate in Douyin interactive activities. They will receive a series of privileges and honors provided by the Douyin platform, such as free trials of new Douyin features, participation in offline activities, etc. The launch of this feature can not only encourage more users to actively participate in Douyin interactions, but also help the Douyin platform better understand user needs and improve user experience.
