侯君集
Late in 626, when Emperor Taizong personally ranked the contributions of the generals and officials in order to grant them fiefs, Emperor Taizong ranked five of them—Fang Xuanling, Zhangsun Wuji, Du, Yuchi Gong, and Hou Junji to be contributors of the highest grade, and Du was created the Duke of Cai. When Emperor Gaozu's cousin Li Shentong () the Prince of Huai'an, himself a key general, objected to being ranked below Fang and Du, stating that Fang and Du, in particular, were only bureaucrats, Emperor Taizong pointed out that it was with their strategies that he was able to become emperor, Li Shentong relented, which led to the other objectors to also cease their objections.
