房玄齢
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—Zhangsun Wuji, Fang Xuanling, Du Ruhui, Yuchi Gong, and Hou Junji to be contributors of the highest grade, and Zhangsun was created the Duke of Qi. As Zhangsun was both a great contributor to his victory and a close relative, Emperor Taizong was particularly close to him, allowing Zhangsun to enter the palace frequently.
