His clan became an honored one, as his younger brother Yang Shidao married Emperor Gaozu's daughter Princess Guiyang; his niece was wife and princess of Li Yuanji and later became a favorite concubine of Emperor Taizong; and his nephew Yang Sijing (楊思敬) married another daughter of Emperor Gaozu, the Princess Anping.
