Regarding Yang Yang's message, I would like to say that the school's recording and broadcasting still needs to be improved. This is true. Of course, the school is also working hard to improve. Maybe watching the live broadcasting will make people feel this way, but the key is to learn knowledge. In terms of teachers, I think there are still many excellent teachers in this school. They have daily teaching materials and textbooks, and there are very good teachers and a good teaching atmosphere. If you want to make money, you need to improve your own abilities. You should have your own market positioning. If you don't study hard, you can't make money. I think it is necessary to study hard and update knowledge. But the school's software still needs to be improved, hoping to provide more good teaching software and latest knowledge.
