Weibo's soul-killing means adding the word "soul-killing" to Weibo's profile, so that others can't find your ID when searching your name. This practice originated from 20 18. At that time, the work "Soul of the Town" with the theme of beauty was taken off the shelf for rectification, and words such as "Soul of the Town", "Soul of the Town" and "gay" were all judged as restricted words, and users involved in related introductions would not search and display it. To avoid being searched, some netizens will add the word "Zhenhun" to Weibo's profile to avoid search restrictions.
