You can see Zhuge Liang's character by borrowing arrows from the grass boat. Urgent! ! ! !

A clever plan to borrow arrows from all sides. He counted the weather and knew that there must be heavy fog at four o'clock on the third day; He came up with a way to collect arrows. Twenty ships were connected by ropes, lined up and collected arrows on both sides. He was also a good man. Knowing that Lu Su was honest and trustworthy, he borrowed a boat from him. Knowing that Zhou Yu was smart, he didn't let Lu Su borrow a boat from Zhou Yu. Knowing that Cao Cao was cautious and suspicious, he couldn't see the truth clearly and wouldn't send troops easily, so he made a big noise and pretended to attack Cao Cao in a foggy night. He even thought that Zhou Yu would be puzzled after taking the arrow, but he would never ask the reason directly, so he let Lu Su take the arrow in the same boat as a witness.
