Xiao Daocheng was a general in the Southern Song Dynasty and served as a general of the right army during the reign of Emperor Ming of Song Dynasty. In the second year of Song Dynasty (474), Liu Xiufan, the king of Guiyang, was pacified, and he was appointed as the secretariat of Jiangzhou, the official to the public, and moved to China as the leading general, mastering the guards and supervising the military affairs of Wuzhou, and gradually gained power. In the fifth year of Song and Yuan Dynasties (477), Xiao Daocheng made Liu Zhun succeed to the throne and made him King of Qi. In the first year of Qi Jianyuan (479), Xiao Daocheng forced Song to retreat and destroyed Song Jianqi. Gaiyuan Jianyuan originated from the theory of divination, and there is a folk saying that "the golden knife is sharp and the blade is cut together", which means that "Qi" will replace "Liu Song".
After the Qi Emperor Xiao Ze succeeded to the throne, he implemented the household registration inspection policy. Those accounts that are considered to be fake must be returned to the local area, which is called "refusing accounts". Although the audit policy has increased taxes, it has seriously hurt the interests of landlords among civilians. In the third year of Qi Yongming (485), Fuyang Tang Yuzhi rebelled. In the eighth year of Qi Yongming (490), Emperor Wu of Qi was forced to compromise and declared "giving up" invalid. Emperor Wu of Qi basically inherited the style of Emperor Gao of Qi, advocated frugality to the outside world, and maintained border peace with the Northern Wei Dynasty, which greatly enhanced the national strength of Southern Qi, and was called "the rule of Yongming" in history. After the death of Emperor Wu of Qi, cannibalism occurred from time to time in Southern Qi, and the national political situation was turbulent.
