Is Li Boming Yang's mental journey credible?

Not a liar. They are all certified, so they are not liars. Li Bo, a teacher of Yang Ming's mind-wandering education class, Li Bo, a high school math teacher, and Tik Tok's big V with nearly 2 million fans are all parents of Precision Bao. The contents of the lectures are all children's education issues that these groups care about, and they are good at using vivid language and expressions to make everyone understand abstract truth.
