Question: Did Dong Cheng have any children when he was executed? Passage:Liu Bei and his oath brothers Guan Yu and Zhang Fei swore allegiance to the Han Empire in the Oath of the Peach Garden and pledged to do their best for the people. However, their ambitions were not realised as they did not receive due recognition for helping to suppress the Yellow Turban Rebellion and participating in the campaign against Dong Zhuo. After Liu Bei succeeded Tao Qian as the governor of Xu Province, he offered shelter to Lu Bu, who had just been defeated by Cao Cao. However, Lu Bu betrayed his host, seized control of the province and attacked Liu Bei. Liu Bei combined forces with Cao Cao and defeated Lu Bu at the Battle of Xiapi. Liu Bei then followed Cao Cao back to the imperial capital, Xu, where Emperor Xian honoured him as his "Imperial Uncle". When Cao Cao showed signs that he wanted to usurp the throne, Emperor Xian wrote a secret decree in blood to his father-in-law, Dong Cheng, and ordered him to get rid of Cao. Dong Cheng secretly contacted Liu Bei and others and they planned to assassinate Cao Cao. However, the plot was leaked out and Cao Cao had Dong Cheng and the others arrested and executed along with their families.
