Idiom story
During the period of Emperor Wu of the Han Dynasty, Emperor Wu's grandson Shunliu was imprisoned because of his involvement in Wang Wei, and the jailer Bingji tried his best to protect him. Emperor Wu wanted to kill all the prisoners in the prison, and Bingji risked his life to save them. Later, Liu Shun ascended the throne as Xuan Di, Emperor Wu of the Han Dynasty. Bingji concealed this history, and Xuan Di respected him even more. Chun Wu, a native of Chang 'an, praised Bingji's dedication and infinite achievements in protecting Xuan Di.
