Warrior Lanling-Gao Changgong, surnamed Gao, surnamed Su, long word. (ad？ -573, no birth history, 54 1 is a personal guess).

Long and respectful, soft and powerful, affectionate. In order to be diligent and meticulous, each one is sweet. Although a melon counts as several fruits, it will be with the soldiers. It is mentioned in the Book of the Northern Qi Dynasty, the History of the North, the Monument to the King of Zhongwu in Lanling, Music of the Old Tang Dynasty and Jiahua in Sui and Tang Dynasties.
