Sima Guang Breaking the Vat
Sima Guang was a great statesman and historian in ancient China. He was very clever from an early age.
One day, Sima Guang was playing hide-and-seek with several children in the backyard. There was a large water vat in the yard. It was full of water. When the kids were playing, one child accidentally fell into the vat. Other children were so frightened that they started to run, crying for help. However, Sima Guang was different. He thought it over and then had an idea. He picked up a big stone and threw it at the vat. “Bang!” The vat broke and the water ran out. The kid was saved.
In my opinion, I think we should learn from him. When we are in trouble, we should calm down and find a solution.
