Yang Hu
In 265, after Sima Zhao's son, Sima Yan (Emperor Wu) usurped the throne from the last Cao Wei emperor Cao Huan and established the Jin dynasty (266–420), he appointed Zhang Hua as a Gentleman of the Yellow Gate () and awarded him the title of a Secondary Marquis (). He was promoted to the position of a Master of Writing () later. Around 279 or 280, when the general Yang Hu encouraged Emperor Wu to conquer the Jin dynasty's rival state Eastern Wu, most officials strongly objected but Zhang Hua agreed with Yang Hu and became heavily involved in the strategies and logistic arrangements behind the campaign against Eastern Wu. After the Jin dynasty conquered Eastern Wu in 280, Emperor Wu enfeoffed Zhang Hua as the Marquis of Guangwu () to honour him for his contributions.
