There are many people in this world, so people always classify these various people - for example, if classified by gender, they will be divided into "men" and "women"; if classified by age, they will be divided into three categories: "children", "adults" and "elderly". Of course, these two categories are considered the most basic categories, and there are also some less basic categories, such as Weibo.
The first type of people is called Weibo control. A typical manifestation is when you go to a restaurant to eat or go somewhere to play, the first thing you do is to take out your phone and keep taking pictures, and then keep posting on Weibo.
The second type of people is called people who know Weibo. This type of people are people who know Weibo but don't rely on it very much. The typical behavior is that after seeing Weibo trolls, they act like they are used to it.
The third category of people is called Weibo illiterates. That is, people who don't know anything about Weibo. The typical behavior is that after seeing a Weibo troll, one panics as if seeing a ghost or a dinosaur, and then... Runs away.
And Ling Sijia is a typical first type of person.
