Once upon a time in ancient China, there was a young boy named Sima Guang. He was known for his intelligence and quick thinking. One day, while playing with his friends near a large water jar in the garden, one of the children accidentally fell into the jar. The water was deep, and the child was struggling to stay above the surface.

The other children were frightened and started to scream for help. But instead of panicking, Sima Guang thought quickly. He looked around and saw a big rock nearby. Without hesitation, he picked up the rock and threw it at the jar with all his might. The jar shattered, and the water poured out, saving the child inside.

This story has been passed down through generations as an example of resourcefulness and courage. Even today, people remember Sima Guang for his bravery and quick action.

This simple yet powerful tale not only teaches us about problem-solving but also emphasizes the importance of staying calm under pressure. It's a story that resonates across cultures and languages, making it a timeless lesson for everyone.
