Meritorious education is simply false. At first, I found something was wrong, because there was no teacher to give a lecture on the spot, only recording and broadcasting, only sound, and no one could be seen. As a result, I found that the video did not match the information sent, so I bought an official textbook. I found that I didn't deserve more, and then I began to doubt. I checked my qualifications online. Found that there is no qualification at all. It is a lie.
