Give three stories and personality characteristics of Yang Zhi, a blue-faced beast in Water Margin.
Green-faced beast Beijing fights with Wu Zhi, takes Yang Zhi as the birth class, and sells knives. Yang Zhi is clever and alert. He understands the situation in the world: "It must be better now than in peacetime", and he also understands the situation along the way. He knew that Huangnigang was "the haunt of strongmen" and "leisure is often in peacetime; Come out to rob people in broad daylight, and the embroidery way is like this. " His judgment is completely correct. He found someone poking around in the opposite pine forest and asked questions at once. As soon as he saw that the soldiers were buying wine, he stopped it categorically, fearing that he would be cheated by sweaty drugs. It really happened. Wu Yong's plan really used sweating medicine. However, we can only say that Yang Zhi is "quite" smart, not "very" smart. All precautions should be taken just in case, too much is too late. Even if there are no drugs in the wine, you still don't need insurance. Wu used them to cheat, and Yang Zhi "watched the fire from the other side", knowing only one and not the other. He only "ate half a ladle and thought it was delicious". I don't think about it. Why did the second man grab a ladle of wine and pour it into the bucket? Are there any other articles about this move? He was blindfolded by Wu Yong's hands and feet and was robbed. It can be seen that his cleverness is slightly inferior to that of Wu Yong. Yang Zhi's more fatal weakness is that he is not good at leading troops and dealing with relationships. It is good to call him "arrogant". In today's words, he was a warlord and disciplined with sticks, so that his hungry people complained all the way and left Germany. He has no prestige in the escort team, so he doesn't pay attention to coordinating his relationship with the old coach Hou Yu and doesn't know how to win people's hearts. He didn't make it clear in advance, and he didn't stipulate the discipline. Of course, he can't let everyone work together to overcome difficulties. Only by beating and cursing, in the end, the command was deadlocked. When they arrived at Huangnigang, Yang Zhi was completely isolated.
