Zhuge Liang in the Romance of the Three Kingdoms can borrow the east wind. Why didn't Zhuge Liang know it would rain when he burned Sima Yi?

1, judging from the event:

Borrowing the east wind means that Zhuge Liang observes the sky at night and finds that the wind direction will change in a few days. In the south of the Yangtze River, the climate is very regular due to the subtropical monsoon climate. If you read the novel carefully, you will find an explanation in it. In fact, everyone in Cao Cao's camp knows that sometimes there will be southeast winds. But this plan was planned by Sun Liu Lianjun, so they took this incident into account when designing the fire. Even if Cao Jun knew this phenomenon, he wouldn't easily associate it with fake surrender and artillery attack, let alone prevent it in advance. Therefore, Zhuge Liang used the east wind to predict that the timing of Huang Gai's false surrender could just be arranged when the southeast wind blew.

The upper valley is located in the Weihe River basin, which belongs to the continental climate, mostly short-term rainstorm, which is difficult to predict (just like the maritime climate in Britain, it is difficult to predict rainfall with modern technology). Moreover, the rain may also be short-term rain caused by the condensation of smoke rising from the fire into small water droplets, which Zhuge Liang did not expect.

2. From the author's point of view:

In Romance of the Three Kingdoms, Liu was revered and Cao was relegated. In order to reflect Zhuge Liang's wisdom, the incident of borrowing Dongfeng/Fangshanggu is fictional (not necessarily fictional, but even if these things exist, they will not be preserved: the former has nothing to do with the overall situation, and it is impossible for the core members involved in the war to know; The latter was completely defeated by Sima Yi, the emperor of the Jin Dynasty, Xuan Di. Of course, historians of the Jin Dynasty dare not write, and records of other countries will not be preserved. Joining Dongfeng not only improved Zhuge Liang's "divine power", but also did not conflict with history (what history can determine is that Cao Cao defeated Chibi, and the specific process is not necessarily accurate, and opinions vary). The enemy of Shanggu is Sima Yi, who is obviously not dead in history. There are other important acts after Zhuge Liang's death. Of course, you can't write him to death. However, in order to show Zhuge Liang's strategy, Sima Yi was the best target candidate, which created a contradiction: Sima Yi was in danger and he was alive, so "rain from heaven" was born. This technique is similar to the "God-given Spring" after Si Mazhao was besieged by Jiang Wei.

Second, the introduction:

1, Zhuge Liang (181-23410-8), named Wolong (also known as), Han nationality, was born in Yang Du, Xuzhou (now yinan county, Linyi City, Shandong Province), an outstanding prime minister of Shu and Han in the Three Kingdoms period.

Zhuge Liang lost his father in his childhood, went to Nanyang with his uncle, and then followed Liu Bei, laying the foundation for Liu Bei to have one of the three realms. After the founding of People's Republic of China (PRC), he was named Hou of Wuxiang, consoling the people at home, showing etiquette, appointing officials, surrendering to power, being sincere and fair, and uniting with Wu to resist Wei. In order to realize the political ideal of recovering the Han Dynasty, he made several northern expeditions, but all failed for lack of good generals, and finally died in Wuzhangyuan. Liu Chan regarded him as a loyal minister, so later generations often referred to Zhuge Liang as a loyal minister and Zhuge Wuhou. Because of his military ability, the Eastern Jin regime named him King Wuxing.

2. Sima Yi (179—25 1 September 7th, 2008) was born in Xiaojinli, wen county, Hanoi (now wen county, Jiaozuo City, Henan Province).

Posthumous title Wenxuan; The second son Sima Zhao made Sima Yi the queen of Jin and made Sima Yi Wang Xuan.
