How does Zhuge Liang view astronomical phenomena?

Zhuge Liang's observation of the night sky is scientific and reasonable, knowing that there is a grass boat to borrow arrows and that there is a wind to worship the east wind. But seeing the astronomical phenomena, I knew that Cao Cao was not worthy of death, and sent Guan Yu to Huarong Road, knowing that Pang Shiyuan would rest when he saw the stars, which was a bit like the traditional astronomy and geography in China. Five lines of gossip and Taoism belong to simple science, and science and superstition are mixed together. From a scientific point of view, Kong Ming should be able to predict the weather, which is unlikely to be accidental, because Zhuge Liang is sure that there will be an east wind that night. According to what he learned in Longzhong, Zhuge Liang judged the Eight Diagrams and the Twelve Qi Festival through his erudition, and combined his personal judgment with the climate along Jiangdong and the Yangtze River. It is inferred that there will be an easterly wind in 1 1 month. Because in winter, if the weather changes regularly, it will rain after a warm period of time, and then the northwest wind will hang up, and then the weather will be fine and cold, and then it will gradually warm up, and then it will probably blow northwest wind. Zhuge Liang guessed this rule. Zhuge Liang ordered Guan Gong to capture Cao Cao in Huarong Road. As a result, Guan Gong released Cao Cao. Even Liu Bei saw it and asked Zhuge Liang, why did you send Guan Gong to see Cao Cao when you knew that Guan Gong was old? Zhuge Liang made it clear that Cao Cao's life should not be decided by watching the celestial phenomena at night, so he sent Guan Yu to send a letter for mercy and let Cao Cao go. Liu Bei can do nothing. Now we all know that astronomical phenomena have nothing to do with people. This is Zhuge Liang lying to Liu Bei. Why did Zhuge Liang cheat Liu Bei? Why did you let Cao Cao go? According to the situation at that time, only three pillars were relatively stable. If Cao Cao was arrested and killed at that time, Liu Bei's inheritance was unstable at that time, and Sun Quan sent troops to Xuchang, it would be a great event, and Liu Bei had no land and no city, which would be won by Sun Quan soon. So let Cao Cao go, and Liu Bei still has a way out. If he is killed, it will be difficult for him to protect himself. According to the novel, Liu Bei only had Jiangxia County at that time, and it was a tiny place. How can he compete with a strong enemy! And Cao Cao's 830 thousand army was destroyed, and its strength was greatly damaged. It can hardly go any further south. At that time, Zhuge Liang wanted to divide the world into three parts, and Wu Dong (Lu Su also proposed to divide the world into three parts in history) also wanted to gain a foothold. Therefore, in order to realize the ideal of "restoring the Han Dynasty", Liu Bei had to stand on his own feet. If Cao Cao was killed, the northern Cao Wei Group would be leaderless, and Sun Quan was in high spirits at that time, so as long as Sun Quan went north to attack Cao Wei, it would be a piece of cake, and then two-thirds of Liu Bei's world would be wasted and his life would be in jeopardy. Therefore, Zhuge Liang arranged this for Liu Bei's future consideration. If Guan Yu was not guarding Huarong Road and Zhang Fei and Zhao Yun were guarding it, Cao Cao would die. After Cao Cao's death, there will be chaos in the north, and the north will return to the situation of hegemony. At this time, it is indeed possible for Sun Quan to attack the Central Plains northward. If Sun Quan invades the Central Plains and occupies Xudu, then Sun Quan will choose whether to establish or abolish the Han Constitution. I think Sun Quan is most likely to choose the former. If Emperor Xian of Han Dynasty is abolished, he will become another Dong Zhuo, or even a public enemy of other forces. Besides, if Sun Quan marched into the Central Plains, wouldn't he be afraid of other forces uniting against him? Aren't you afraid that Liu Bei of Jiangxia stabbed him in the back? Therefore, Sun Quan's Northern Expedition is unlikely.

Zhuge Liang is a man who is good at making decisions, but his talent is not an improvisation without foundation. He is good at observing the sky at night, predicting the gods and so on. For modern people, people pay more attention to Zhuge Liang's correct decision-making based on fully, accurately and timely grasping the objective situation. Before many battles, he either sent "seiko" or "spy", or captured soldiers with fallen generals, or personally investigated the enemy's deployment, inquired about the quality, skills and psychology of enemy generals, observed the terrain, and then worked out a favorable operational plan to defeat the enemy. On the eve of Battle of Red Cliffs, it was in the process of Cao Cao's going south to Jingzhou that he experienced several wars with Cao Jun and accurately grasped the advantages and disadvantages of both sides, thus making a correct prediction that Cao Cao would fail. The reason why Longzhongdui makes an incisive and pertinent analysis of world events embodies Zhuge Liang's huge and long-term labor. Zhuge Liang, who is ambitious and temporarily lives in seclusion in the mountains, collects information from all sides and understands various social, political and military trends. He usually studies hard, and his reading method is "just reading the outline", so he has a wide range of knowledge and a deep understanding. He pays attention to communication. Cui from Yingzhou and Boling, Xu Shu and Meng from Runan are all his close friends. After that, he met Pang Tong, known as "Feng Chu", and Si Mahui, a Taoist water mirror. His brother is involved in the secrets of political affairs, and his brother-in-law Zhuge Jun and his father-in-law Huang are knowledgeable and sharp-minded. Zhuge Liang exchanged letters with these people or got together to talk, forming a modern intelligence network like a cloud. Zhuge Liang, who is interested in the world, is the advanced storage and processing center of this network. Zhuge Liang also likes to travel in clouds, so as to explore the geography of mountains and rivers and understand the local conditions, customs and climate products. So Zhuge Liang's immaturity is false, but the known world is true. This is not prescient, but embodies the epistemological truth that knowledge comes from practice. Xu Shu left Liu Bei in tears and went straight to Wollongong, pleading with Zhuge Liang to help Liu Bei. Although Zhuge Liang refused on the surface, he actually wanted to do further investigation and study. After that, for a period of time, he ran around for several days, making Liu Bei, Guan Yu and Zhang Fei all fail. He wants to further supplement the latest information, and he wants to think twice about the plan to mediate between heaven and earth. When he was lying in the thatched cottage waiting for the third arrival of Liu Bei, Guan Yu and Zhang Fei, his strategic decision to divide the world into three parts was already in his mind. Otherwise, where did you get the 54th state wall chart of Surprise? How could Zhuge Liang laugh it off like a treasure? How could he have just arrived in Xinye, and put forward his first important suggestion to Liu Bei: "When Cao Cao works as a Xuanwu Pool in Jizhou and trains sailors, he will invade Jiangnan." It can make people cross the river to discover the truth. Therefore, decision-making is not a simple summary of information, but a leap in understanding. It needs to analyze and synthesize the objective situation under the guidance of scientific methods. This analysis should follow the following principles. The above examples show that only a comprehensive system can be biased when analyzing and studying the existing information and intelligence; Only by paying attention to comparison can we reveal the differences and contradictions, highlight the advantages and disadvantages of both sides, reduce the uncertainty of various factors and improve the accuracy of prediction.
