The story of 100,000 arrows

This is a story about two wise men — Zhuge Liang and Zhou Yu. The Chinese people have told it for many, many years.

One day, Zhou Yu gave Zhuge Liang an impossible task. He asked him to make 100,000 arrows within ten days. "No problem," Zhuge Liang said. "I'll bring you 100,000 arrows in three days."

Zhuge Liang asked his soldiers to fill 20 large boats with many straw men. In the early morning of the third day, Zhuge Liang's soldiers sailed the boats towards the camps of Cao Cao's army on the other side of the river. The soldiers shouted and beat their drums loudly.

When Cao Cao's soldiers heard the sounds, they thought they were under attack. However, they could not see through the thick fog on the river. Cao Cao ordered his soldiers to shoot arrows towards the sounds of the drums and the shouting. Zhuge Liang's boats were soon full of arrows.

Zhuge Liang's soldiers then turned the boats around and shouted, "Thank you for your arrows, Cao Cao." Zhuge Liang took all these arrows to Zhou Yu. There were more than 100,000 of them.
