And then something happened. Originally, Zhang Kai received the Cao Song family, but it was raining cats and dogs on the way back. So they took shelter from the rain in a small temple and planned to wait until the rain stopped before going on their way. As a result, Cao Song thought his son was not good, so he didn't take Zhang Kai and others seriously and let them wait outside for the rain to stop. Zhang Kai is a military commander, how can he stand this anger, plus him?
When Cao Cao learned about it, he couldn't stand it. In a rage, he sent troops to Xuzhou and killed all the people in Xuzhou without asking indiscriminately. Cao Cao also took this opportunity to occupy Xuzhou. In history, Cao Cao did slaughter Xuzhou, but the specific details were not as shown on TV. The unknown secret is that Cao Hao's family was not killed by Zhang Kai, but by Tao Qian. At that time, Cao Hao took his family to Xuchang to find Cao Cao. Instead of going to Xuzhou, he went to Taishan in Shandong. Cao Cao also sent Taishan guards to meet Cao Hao's family. I didn't expect that Tao Qian had been dissatisfied with Cao Cao, so I wanted to take this opportunity to get back at him. Tao Qian took his army to Mount Tai to kill Cao Hao's family. When Cao Cao learned about this, he hated Tao Qian's guts. At that time, he had lost his mind and ignored it. He led troops to Xuzhou, killing the city.
