First, this is indeed disguised propaganda.
I have to say that this is a good way of publicity. The role of Tian Yulan in TV series is really distressing and annoying. She not only forces her children to study, but also likes to compare them. David told her to shut up because she really talks a lot and sometimes hurts others because of inappropriate language. Anyone who has seen this play should feel this way. Even as a public figure, she will feel the same way. They don't usually post things on social platforms. After all, a little carelessness will attract the attention of fans, and no matter what they do, they will look at them with a magnifying glass. Therefore, in David's Weibo, this TV series is really being promoted in disguise.
Second, the words and deeds of public figures will be concerned.
Many times, public figures will not casually post some comments on social platforms. The content they post will be evaluated and reviewed by relevant staff, and will be released only if there is no problem. They don't usually make such comments. In the case of the hit of this drama, David's release of this passage is really propaganda, and there are indeed many people who have noticed Xiao Shede's story because of this topic.
So David's practice is really promoting Xiao Shede, so that more people can know and watch TV series.
