Both of them have their own strong points, vivid and vivid, and Chen's ability to give lectures is even more remarkable. He thinks that the system of training teachers in the past is good. He also said that he brought out many teachers in the online school, and he didn't use PPT in the online school. Courseware is made by himself and summarized by himself, and the order of speech in some places is more reasonable for him. So objectively speaking, Brother Fei is a little lacking in the topic of speaking, not because of his ability. However, I feel that he treats all the students at the upper-middle level, and the lecture speed is super fast (but it can be played back if they don't understand). It is difficult for students who are a little slow to keep up, but it is still very good on the whole, and according to our tutor, it is as difficult to grab Gefei's class as Spring Festival travel rush's. Ha ha ha ha ha ha ha ha ha. In the final review stage, I personally think it doesn't matter which teacher I apply to, but I strongly recommend applying to Gefei's class where he just started studying chemistry. how shall I put it,
