It was Tao Kan who named Tao Kan as the ancestor of Tao surname in Bazhou, Hunan. In 300 AD, at the end of the Western Jin Dynasty, Tao Kan, the thirteenth grandson of Tao She, came here from Xunyang as the magistrate of Wugang County, becoming the first Tao to set foot on the hot land of Hunan.

13 years later, Kan Gong re-entered Hunan to quell the Du Fu riots and fought in today's Changsha-Zhuzhou-Xiangtan area for three years. Since then until today, he has never left this land. As the commander-in-chief of the Jin Dynasty, the commander-in-chief of eight states, the fief and now the Duke of Changsha in half of Hunan, Huxiang was under his rule before his death, and finally returned to Sri Lanka to bury his bones.

Kan Gong was also the first person to spread the branches and leaves of the Dow family in Xunyang. His second generation of seventeen people multiplied normally, accounting for 70% of all pottery today. 1838, Eight Towns in Huxiang were joined by Dow, and the ancestral hall was built in the provincial capital.
