Pei Ju
Emperor Gaozu created Pei Ju the Duke of Anyi and had him serve as the head of his son and crown prince Li Jiancheng's household. He also had Pei and Yu Shinan (Yu Shiji's brother) draft regulations on various ceremonies, and the regulations were described as appropriate and praised by scholars. In 624, he was made acting "Shizhong" (侍中) -- the head of the examination bureau of the government (門下省, "Menxia Sheng") and a post considered one for a chancellor.
