Jiang Shuihan has loved literature since he was a child, but the most knowledgeable retired teacher in Jiang Shuihan's village said that literature and history are out of date in today's China, and science and engineering are the most in line with the trend. This retired teacher also gave a thorough analysis to Jiang Shuihan, the only person in the village who could go to high school, from the right time, place and people. In detail, Jiang Shuihan naturally read so many books for nothing, and saw through this person's old-fashioned and outdated thinking at a glance. However, Jiang Shuihan also learned from other books that the most intolerable thing for Chinese people is disrespect, especially when juniors treat elders, and subordinates treat superiors. If there is the slightest arrogance, it is a big taboo. So on the surface one obeys this person's words and then writes articles to criticize them later. This seems to be a trick that Chinese literati have tried many times, but it is also normal. We often say that "rituals collapse and music collapses". The use of the word "collapse" shows that the word "ritual" itself is extremely heavy and cannot be easily moved away. A gangster who is not polite is naturally as light as a feather in comparison and is about to be blown away at any time, so the gangster is called "A Fei".
