In order to express his gratitude to the late emperor for knowing him, Chu Xiao led 150,000 troops to the north to fight against the Hu tribe. In six years, he made great military exploits and was granted the title of King of Zhenbei by the late emperor!

In the same year, Emperor Qing Zheng Tai came to power.
