On the way back to Li, Ji Ji died on the road. When he arrived in Beijing, Ren Heng was sentenced to the third subject. Out of filial piety, he left his hometown. In addition to serving, Fan became the special envoy of the town and the country, and recruited Song as the secretary. Chang (930 ~ 933) was an old school of the Ming Dynasty, and the king of Qin was in a state of lawlessness. Jin Gaozu, the deputy envoy of the Sixth Army, was afraid of getting into trouble and asked to leave the city. At this time, the Khitan invaded Yanmen, and Ming Zongxuan wanted to keep Taiyuan, and Jin Gaozu wanted to go. Fan and others wanted to send Kang Yicheng, and the right one said, "Taiyuan, the north gate of the country, wants to send an important official, and it must be Shi Jingtang!" Everyone agrees. Jin Gaozu thanked him very much and secretly sent someone to thank him, hoping that he would always help him achieve great things.
The emperor died, he succeeded to the throne, and he held the Tang Dynasty in his palm. In the past, Emperor Gaozu was in charge of the army in the State of Jin, and he was the commander-in-chief of the Guards. On an equal footing with Du Zhongwei, Emperor Gaozu felt ashamed. Later, Emperor Gaozu guarded Taiyuan and changed him into a bodyguard. Song also praised Wei-worshipping talents many times, so Emperor Gaozu thought that Song rejected himself and hated him very much. Song eventually called Chongwei to lead the army, but Yu Zhong was defeated by Qidan and Jin Wu.
Qidan Luye Deguang entered the capital, and Deguang repeatedly heard Yan Guang and others praise him as a man. When he entered Beijing, he said to people, "I conquered the Southern Dynasties only to get a man named Bo." So he was promoted to the prince's teacher. When Qidan returned to the north, he ordered the whole family to stay in the town. Later, Ma Yong gave up the town and state, and she was able to return to Beijing. Emperor Gaozu never liked Song, and Song was framed by people who hated him, saying that he was valued by the Qidan. Therefore, Song was always cautious when he met the powerful ministers of the Han Dynasty, and did not dare to offend them.
Emperor gaozu entered Beijing and gave his house to Su Jifeng. Yan Ge, a servant of Yu Di Island, often swallowed money when doing business for Du Yu, and Du Yu whipped him. In the evening, Yan Yu ran to Li Chenggu in Ji Feng. At that time, Gaozu will be buried in Lingrui, and Li Shouzhen will rebel in the river. Cheng told Yan Yu to report that Song and his nephew Wang Ning discussed setting fire to the capital with the help of Shanling, and plotted a rebellion with Shouzhen with wax pill letters. When Song was locked in the prison of the Guards, he knew that he would die, so he was forced to admit it and was finally punished by the clan.
Song Pingping befriended the academician Xu Taifu. Later, Zhou Taizu became emperor. The teacher ordered the Prime Minister Feng Dao to kill Ge. Feng Dao thought it was difficult to kill him on the grounds that he had been pardoned many times. When Wang Jun, the envoy of the Tang Dynasty, heard about it, he praised the loyalty of a teacher, which killed Yan Yu.
