In the third year of Taihe, there was a rebellion in the border areas. Song Yu led his army to put down the rebellion, but the late emperor died. According to legend, the eldest prince Anlin was located. The following year, the country's name was changed to Yuantai, and General Song Yu was granted the title of Marquis of Yuan'an. At this point, the people can live and work in peace and contentment again.
