The teaching mode is different from the traditional one, except that technology will talk about something in the workplace. When students are tired of studying, they will be encouraged to learn more. Because of this, some people misunderstand their sentimentality, while others are not ideal. There is no guarantee that everything will be perfect, only that we will do our best. Of course, we also accept suggestions from some colleagues or classmates that we need to improve, but we don't accept malicious slander. I hope everyone will do it.
