So, a long long time ago, there was a big fight between two groups of people called the Wei and the Shu. They wanted to control a place called Didao, which was very important because it had a lot of resources like food and water.
The Wei had a very big army and they were very strong, but the Shu had a very smart general named Zhuge Liang. Zhuge Liang came up with a plan that was like a big puzzle. He told his soldiers to build a lot of fake walls and hide behind them. The Wei army was very confused because they didn't know where the Shu army was hiding.
But, one day, a man from the Wei army named Pang De saw a mouse running into one of the fake walls. He realized that it was fake and told his leader, Cao Cao. Cao Cao was very smart too and he made a new plan. He sent his best soldiers to attack the real wall where the Shu army was hiding.
The Shu army was very surprised and they didn't know what to do. But, Zhuge Liang had a secret weapon. He had a lot of straw and grass and he set it on fire. The smoke made it very hard for the Wei army to see and breathe. The Shu army was able to escape because of the smoke.
In the end, the Shu army won the battle of Didao because they had a very smart general who came up with a tricky plan and a secret weapon.
