楊諒
In spring 600, with Ashina Dianjue, who had by now become Tujue's khan, attacking the borders, Emperor Wen sent Yang Guang, Yang Su the Duke of Yue, Yang Guang's brother Yang Liang the Prince of Han, and Shi Wansui () the Duke of Taiping, against Tujue, and they were largely successful against Ashina Dianjue, protecting the Qimin Khan Ashina Rangan, whom Sui supported, from Ashina Dianjue's attack.
