杜如晦
After the Tang dynasty replaced the short-lived Sui, Kong Yingda became one of the "Eighteen Scholars" in the court of Emperor Taizong of Tang, along with the likes of Du Ruhui and Fang Xuanling. He served in several top positions of the Imperial Academy, and participated in the composition of the "Book of Sui", the official history of the Sui dynasty. The emperor awarded him the nobility rank of viscount.
