Expand list, an Internet buzzword, is a slang term for those born in 2000, which means requesting to expand the friend list, which is equivalent to making new friends. Among the online platforms frequented by post-00s generation such as QQ Tribe, Baidu Tieba, Weibo, etc., the content “seeking to expand the list” is the most common. In the comments on the "Seeking Expansion List" post, you usually put your basic information and information tags to highlight your personality, and sometimes you will also attach a good-looking photo of yourself.

The list expansion originated before the posts in Li Gongjun’s bar were cleared for the second time. The bar prohibited members from leaving any contact information, and all friendship-type posts would be blocked by the administrator. Therefore, the members in the bar called the friendship posts "Expansion" later evolved into a common code word for some people born in 1995-05.
