Seven-star platform offering sacrifices to the wind

Zhuge Sacrifice in Romance was invented by Luo Guanzhong to show Zhuge Liang's wisdom. The red cliff fire did happen, and Zhuge Liang did contribute. He didn't borrow the east wind, but accurately predicted its appearance. He knows astronomy above and geography below, and it is the turn of the season. Zhuge Liang calculated the time of the east wind just like the weather forecast, which enabled Zhou Yu to seize the opportunity of burning Chibi and contribute to the success of the war.
