There are countless historical stories recorded in textbooks, such as Kong Rong, who is humble, Zu Di, who smells chicken dancing, and Sima Guang, who smashes the cylinder. To this day, only Sima Guang's smashing of the cylinder remains in my mind, and the significance of these historical stories is not only to let us understand history at that time, but also to draw the experience and wisdom of predecessors from these stories.

The vast courtyard was steaming in the middle of summer, and a group of children were playing in the middle of it, and naturally approached the water tank, but one of them fell into the water tank, and When everyone panicked, Sima Guang did not hesitate to smash the cylinder to save people. This is the story of Sima Guang smashing the cylinder, but in order to highlight Sima Guang's wit and bravery, the former people did not mention anything about this rescued child, and the story ended with "The child was saved", and the child had no name after all.
In fact, the person sima Guang saved at the beginning was called Shangguan Shangguang, Shangguan Shangguang was intelligent since childhood, and he read very well, which is equivalent to our current academic bully. Such an excellent him, of course, to participate in the scientific examination is also a piece of cake, all the way to the top of the high, smoothly pass the examination in the soldier. But his official fortunes were a little worse, and later he had no intention of staying in the official field, so he chose to return to his hometown.
Later, he became a very famous businessman. Shangguan Shangguang never forgot Sima Guang after he developed, but Sima Guang, as a Shangshu Zuo servant and a servant under the door, was certainly not short of money, and Sima Guang's character would not accept it, so Shangguan Shangguang established a gratitude pavilion to show gratitude, and he also always taught posterity to remember Sima Guang's great kindness.
The historical records of Shangguan Shangguang are also mostly political matters, and the story of "Sima Guang smashing the cylinder" appears more in some primary school textbooks, so some records about Shangguan Shangguang are also erased. Because it was beyond the cognition of Fan Tao, their age.
