What is the main reason why Yang Zhi lost his birth class?

Subjective aspect: Yang Zhi was too strict with porters, complaining from top to bottom of the old governor's management and refusing to obey his orders. The result was cheated by Wu Yong and others.

Objectively speaking, the weather is hot, and Yang Zhi and his party are thirsty and eager to find something to quench their thirst. The result was cheated by Wu Yong.

"Taking a Birth Program by Intelligence" tells how Yang Zhi escorted a birth program to Tokyo, and was captured by Chao Gai Wu Yong and others (Huang Nigang) on the way. "Outwit the birth program" is the collective action of the peasant uprising and the beginning of the heroes' meeting in Liangshanpo.

In order to return to the imperial court, Yang Zhi accepted the important task of escorting the birth class. In order to avoid accidents, he is careful everywhere. I began to travel while it was cold, and then went to the desolate mountain road. For safety reasons, I changed to travel in hot weather. This is a preventive measure that conforms to the terrain, but neither the military nor the Han people can understand it.

Finally, even the old people began to complain, so the soldiers and Han people did not listen to Yang Zhi's insults and insisted on resting in the Huangnigang Woods where the strongmen haunted. At this time, classical figures dressed as businessmen appeared. Subsequently, Bai Sheng also picked up the mountain liquor. The soldier wanted to buy wine, but Yang Zhi suspected that there was antiperspirant in the wine and refused to buy it. Bai Sheng immediately said not to sell. Then, Chao Gai and others came to eat a bucket first, let Yang Zhi relax his vigilance, and used the spoon of wine as a cover to drug the wine.

Bai Sheng also played without flaw. At this time, Yang Zhi began to relax and agreed to buy it. But Bai Sheng refused to sell it, which made Yang Zhi and others completely relaxed their vigilance, bought wine after drinking, and finally all of them were stunned by roofies, and the birth class was robbed.

In this passage, the battle of wits between Yang Zhi and Chao Gai is always going on nervously, but it is not obvious, and there is no fierce conflict from beginning to end, because we have no way of knowing that the guests of those traffickers are Chao Gai and others, and the struggle between them is also covered up by the superficial struggle between "soldiers buy wine" and "Yang Zhi gives up drinking".

Yang Zhi is between disobedient soldiers who want to drink and classicists who want to lure them to drink. Although he is cautious, he is also struggling to cope. More importantly, Chao Gai and others are better at "planning". No matter how Yang Zhi guesses and how to guard against it, they all seem to fully understand Yang Zhi's psychology. They have a way to resist, and it's fake. Really, everything is ahead.
