Yang hu (22 1-278) was born in Chengnan, Taishan. A famous strategist, politician and writer. Erudite, honest and upright, married Xia Houba's daughter. Cao Shuang and Si Mazhao were rejected many times, and later they were enshrined in imperial cars. When Si Mazhao established the five-grade knighthood system, he set up an outstanding Dapingzi, and kept it secret from Xun Xu. After the Jin and Wei Dynasties, when they wanted to swallow Wu, they ordered Yang Hucheng to take Xiangyang to take command of Jingzhou's military. In the following ten years, Yang Hucheng promoted his studies by farming, which won the hearts of the military and civilians. On the one hand, they made military and material preparations for attacking Wu, and wrote a letter to crusade against Wu after Kang's death, but it was opposed by his ministers. In the fourth year of Xianning (278), yang hu returned to Luoyang and died in November of the same year. Before his death, he recommended Du Yu as his peer.
