Everyone knows that Zhuge Liang used the east wind to burn Chibi, so how did he borrow the east wind?

Zhuge Liang is a wizard who knows astronomy above and geography below. After observing the celestial phenomena by the river, Zhuge Liang figured out when there would be an east wind on the river, so he made up a lie to let the viceroy borrow the east wind, which was actually a weather forecast.

I know Zhuge Liang was a wizard in the Three Kingdoms period. He knows astronomy above and geography below. He is also a scientist, mechanic, politician, strategist and so on. Zhuge Liang actually observed the weather and predicted the time of the east wind according to the change of the weather at that time, so he told Zhou Yu that the time of borrowing the east wind was particularly accurate, and if he was asked to be a day earlier or a day later, it would not work. So he didn't borrow the east wind, but predicted it according to the weather change. In fact, Zhuge Liang not only used meteorological knowledge in borrowing east wind, but also used weather changes in borrowing arrows from grass boats. Let's analyze it.

1. Zhuge Liang inferred the time of the east wind according to the meteorological change. Zhuge Liang and Lu Su stood by the river and watched the weather on the river. They said to Lu Su: Look at the east, there are clouds like dragons. ? In fact, Zhuge Liang had speculated at that time that there would be an east wind blowing on the river on the first day of the first month. Because Zhuge Liang read the Book of Changes, which is our earliest agricultural series. According to the Book of Changes, it's okay to rain and wind.

Second, Zhuge Liang inferred the time of fog in the river according to meteorological changes. Zhuge Liang and Lu Su stood by the river and looked at the clouds in the sky. He said to Lu Su: Look at the east, there are clouds like dragons. ? Everyone did not guess wrong. In fact, Zhuge Liang has speculated that there will be fog on March. That's why he dared to give Zhou Yu a written military order.

Third, Zhuge Liang was not only talented, but also married an inventor's wife. Zhuge Liang is not only a meteorologist, but also a scientist and inventor. He invented the wooden ox and flowing horse to help Shu transport grain and grass. His wife is the best inventor, far better than Zhuge Liang. Zhuge Liang wouldn't have married Huang Yueying if he hadn't taken a fancy to her talent.

Look at the east, there are clouds like dragons. Someone must want to give me a good news.
