Zhangsun Wuji
In 637, as part of Emperor Taizong's scheme to bestow prefectures on his relatives and great generals and officials as their permanent domains, Gao's title was changed to Duke of Shen, and he was given the post of a prefectural prefect for his heirs to inherit. Soon, however, with many objections to the system, the strongest of which came from Zhangsun Wuji, Emperor Taizong cancelled the scheme, although Gao's title remained Duke of Shen.
