In 725, Emperor Xuanzong gave Yuwen the additional office as deputy minister of census (戶部侍郎, "Hubu Shilang"). He also decreed that the grains submitted as taxes by the census evaders were to be put aside in storage in case of famine, and also established agriculture promotion offices in the prefectures and counties to try to enhance agriculture. Later that year, when Emperor Xuanzong suspected the ministry of civil service affairs to be unfair in its selection of officials, Yuwen suggested that he appoint 10 officials to review the selections, and then further review the 10 examiners' decisions. Emperor Xuanzong agreed and carried out the plan, despite objections submitted by the official Wu Jing (吳兢), although in 726 he stopped the scheme.
