Yicheng: Yicheng should be the most publicized national grid examination and training institution in the market at present. Qian Wen said that education has also been investigated on various platforms, and many students have signed up for classes.

Hengzhen: Actually, Hengzhen is similar to Cheng Yi, with great publicity, but slightly more difficult to practice, which is not suitable for students who have just started preparing for the exam. Generally speaking, this exercise feels more difficult.

Hongpai: Hongpai will hold online and offline public welfare lectures in all provinces of the country, which is better. Through the lecture, we can have a clearer understanding of this institution. Anyway, there is no charge for public lectures, so it's no harm to go and listen to them. The students who listened to the lecture reported that the teacher was more professional, so they bought their live class. Online class is a synchronous live broadcast of face-to-face teaching, and the interface is the teacher's courseware with good clarity.
