Because Sima Chu was very kind to the soldiers, the assassin Qian Mu pretended to be ill, and Sima Chu actually took the medicine to see him himself. Qian Mu was very moved, so he gave up the assassination. Sima Chu was originally a member of the royal family. Later, the Sima family was taken away by Emperor Wu of Song, and many Sima family members were killed for fear of revenge. Sima Chu's father was killed by Emperor Wu of Song, and he was forced to hide in a remote place in the Northern Wei Dynasty.

Yuan Di, a Ming Taizu in the Northern Wei Dynasty, thought Liu Yutai was mean, so he chose to be kind to the Sima family. After all, the enemy of my enemy is my friend. So Sima Chu went to Yuan Di in the Ming Dynasty. Sima Chu is also a very talented person. He helped Yuan Di win many battles in the Ming Dynasty. Ming Yuan Di named him the King of Langya, and his position was very high at that time. Sima Chu will never forget the revenge of killing his father, so Sima Chu secretly gathered many people with lofty ideals to take revenge on Emperor Wu of Song.

Emperor Wu of song was very scared after learning the news, so he sent Qian Mu to be undercover. Qian Mu pretended to be a man with lofty ideals, became the guest of Sima Chu, and gradually gained Sima Chu's trust. He felt that the time had come, so he pretended to be ill and led Sima Chu to see him, and then killed Sima Chu. Sima Chu did go to see him, and he personally sent medicine to Qian Mu. Qian Mu was very moved, so he knelt down and said to Sima Chu that he was sent by Emperor Wu of Song to kill him, but he saw Sima Chu.

Sima Chu said to Qian Mu, "If I don't trust anyone, who will take risks with me?" ? Qian Mu was even more moved and decided to follow Sima Chu, and Sima Chu also let bygones be bygones. Later, because Qian Mu was really excellent, he helped Sima Chu a lot and was entrusted with an important task by Sima Chu. Treating others with sincerity can win the sincerity of others. Sima Chu is such a person.
