In the beginning of the founding of the Song Dynasty, Mao Dezu went on a diplomatic mission to Luoyang. Emperor Wu instructed him: Pei Songzhi is a pillar of the state and should not be in charge of border affairs for too long. Now appoint him as the Crown Prince's Washing Horse. It is equivalent to Yin Jingren. You can let him know.
