Du Ruhui
Fang Qiao (; 579–648), courtesy name Xuanling, better known as Fang Xuanling, posthumously known as Duke Wenzhao of Liang, was a Chinese statesman and writer who served as a chancellor under Emperor Taizong in the early Tang dynasty. He was the lead editor of the historical record "Book of Jin" (covering the history of the Jin dynasty (266–420)) and one of the most celebrated Tang dynasty chancellors. He and his colleague, Du Ruhui, were often described as role models for chancellors in imperial China.
