What kind of character traits does Yang Zhi have?

The birthday card was finally taken away. Does this mean that Yang Zhi is a very stupid person? In fact, combined with other chapters describing Yang Zhi in "Water Margin", we can see that Yang Zhi is a shrewd and capable person. Yang Zhijiu was in Jianghu and knew the dangers of escorting birth dates. As soon as he accepted the task, he refused many times. When he couldn't refuse, he made elaborate arrangements: first, he asked to pretend to be an ordinary businessman and travel quietly to avoid making a big fanfare and attracting attention. People paid attention; and later asked Liang Zhongshu to give him the power to mobilize everyone to prevent internal discord and "thieves" taking advantage of the loopholes. Later, on the road, the traveling time was also changed according to different terrains. At first, we traveled while it was cool. Later, when we arrived at the mountain road area where "there were fewer and fewer people living there and few travelers", for the sake of safety, we changed to "get up at Chenpai and rest at Shenshi". We were traveling when the weather was hot, and no one was allowed to walk in Huangni. Rest in the pine forest of the hill. Later, when the soldier wanted to buy wine, he tried every means to stop him. This all reflects Yang Zhi's shrewdness.

So, since Yang Zhi was so careful, why did he fail in the end? Although this aspect is to highlight Wu Yong's cleverness and impeccable strategy, the main reason is the other side of his character: eager for quick success and cruel and arrogant. It was this kind of character that caused him to "swear harshly, or beat him with canes" on his soldiers, which intensified the internal conflicts in the transport team. "A fortress is easiest to break from the inside." With internal strife, failure is inevitable.

Judging from the overall description of Yang Zhi in "Water Margin", Yang Zhi's character has experienced the development process of "frustration - success - disillusionment". Yang Zhiben was "the queen of the third generation of generals". He originally "hoped to use his skills and swords and spears in the court to gain a wife and a son, and also compete with his ancestors." It should be said that he was full of ambitions at first. Not wanting to have a bad fate, he first lost the "Huashi Gang", and then killed the rogue Niu Er in a fit of rage. He was sued and was sent to the army. This was a frustrating period in his life. But unexpectedly, he was a blessing in disguise, and was appreciated by Liang Zhongshu, who took him under his sect, "working diligently in the morning and evening", and entrusted him with the important task of escorting the birthday card. As long as he completes this task, his future will be bright, and his destiny seems to be "coming out of the dark", and he is not far away from the day when he will be satisfied. But "good fortune and misfortune always lie ahead." He cared too much about this mission, fearing that he would let down Liang Zhongshu's love (this is also a bit of the mentality of "a scholar dies for a confidant"), so he was careful everywhere and always cared about it, so he was a little eager for quick success and quick benefits. , a little impatient. And when he was too careful, his mind became rigid. He always suspected that the sweat medicine had been put into the wine, so he waited until others had drunk it before allowing the soldiers to buy it, but he forgot that there might not be a sweat medicine in the wine, and although others had It can prove that there is myrrh in the wine, but it does not necessarily mean that you are innocent. So I lost my birthday plan, and my illusions were finally disillusioned, and I had to go to Liangshan to drop grass
