Sun Qingguo is the most famous, and everyone who works in an office at home knows it. . . As for the director of the Institute of Administrative Sciences, he was originally a provincial exam, and now there are still many questions from Teacher Sun in the provincial exam database. Also, I know that Ji and Liu Jingshan are both good teachers. They are serious and specialize in the written examination of civil servants. I have listened to their classes. They are all very good, but they may be very deep. People who have accumulated experience will feel particularly good after listening to it, especially Mr. Liu Jingshan. The application is particularly practical, unlike some teachers who are flashy. When I applied for the exam, I felt that Mr. Liu Jingshan's method was particularly suitable for the exam. Teacher Wilson's verbal understanding and logical judgment are good; I don't know much about other teachers.
