With the strength of Shu Han, it is not easy to maintain the tripartite confrontation. Northern expedition to Wei is almost impossible. Zhuge Liang insisted on carrying out this task. The task assigned to all soldiers was so arduous that many key personnel fell down because of the heavy burden.

After the first Northern Expedition and Ma Su's Lost Street Pavilion, Zhao Yun also lost to Ji Gu, but did not suffer a big defeat. Romance of the Three Kingdoms says that Zhao Yun was rewarded by Zhuge Liang. The reflection tells us that Zhao Yun was demoted as a general of the town army and died the next year.

Obviously, Zhao Yun's death is related to his old age, overwork and depression after being demoted.

During the third Northern Expedition, Zhang Bao fell into a mountain stream in the fierce battle and broke his head. He was sent to Chengdu for treatment and died soon. The reason why Zhang Bao fell into the mountain stream is related to the trance caused by overwork.

Another general, Guan Xing, did not die before the battle, but died on the eve of the sixth Northern Expedition.

The successive deaths of Zhao Yun, Zhang Bao and Guan Xing show that the burden of Shu soldiers is very heavy.

Faced with high-intensity pressure, some backbones began to learn to be opportunistic. Take Li Yan for example, he is a rare talent. Before Zhuge Liang attacked Meng Huo, he said that Li Yan "could be Lu Xun" and he trusted Li Yan very much. Zhuge Liang came out of Qishan, and Li Yan was responsible for supervising the grain and grass. Because of the difficulty in getting through the middle of Shu, transporting grain and collecting grain, he was worried that he could not successfully complete the task arranged by Zhuge Liang, so he made up a lie and said that Soochow would invade Shu and trick Zhuge Liang into retreating to Hanzhong. Then he lied to Liu Chan, saying, "I have prepared food and grass. I wonder why Prime Minister Zhuge moved back to North Korea? " After the incident was exposed, Li Yan was banished to Shu Ren.

Today, there are still many superior leaders who, like Zhuge Liang, constantly deploy "impossible tasks". Under high pressure, subordinates fell down one after another, and some people began to cheat like Li Yan.

From this perspective, pressure is not always the driving force. If the pressure from the superior is too large, the pressure will become a resistance to progress. This is the case in Zhuge Liang's time, and so is the modern society in which we live.
