Mr. Chen Weigang is a great talent, and Dr. Tsinghua works in Beiyang. His education is also based on Tsinghua's experience. As the saying goes, sophomores in Tsinghua can also do these tricks. What a pity! But its classes are chaotic, students are bored, teachers are unreasonable, and students suffer for a long time. I heard that my predecessors used to scold me on the stage. I wonder if it's credible.

Ha ha! If there is no teacher, students will not regard it as a teacher. If teachers regard life as dirt, then life regards teachers as enemies. I hope Chen Shi will do it sincerely, and it would be great not to do it again.
