First, Sima Guang smashed the cylinder.

Influenced by his father, Sima Guang was smart and studious since childhood. According to historical records, Sima Guang likes reading Zuo Zhuan very much, and often "never stops reading books, never knowing hunger and thirst." At the age of seven, he was able to recite Zuo Zhuan skillfully, and he could clearly tell the historical outline of more than 200 years, indicating that he had a very strong interest in history since he was a child.

In addition, there is another thing that makes Xiao Sima Guang famous in Kyushu. Once, he and his friends were playing in the backyard. There is a big water tank in the yard. A child climbed to the edge of the tank and accidentally fell into the tank factory. The water tank is very deep, and it seems that the child is going to have no roof. When other children saw that something was wrong, they cried and cried in fear and ran outside to ask adults for help. Sima Guang, however, used his quick wits to pick up a big stone from the ground and hit it hard at the water tank. "bang!" The water tank was broken, the water in the tank came out, and the child who was submerged in the water was saved.
