Yong‑jung] (1678‑1735): Reign name of Yinzhen, fourth son of Kangxi, and third emperor of the Qing dynasty (ruled 1723‑1735). Deeply committed to direct involvement in government affairs, Yongzheng launched a vigorous reform of the Qing tax structure. To manage his military campaigns more efficiently in the northwest, he bypassed the cumbersome regular bureaucracy and formed a group of his most trusted grand secretaries which became known as the Grand Council under Yongzheng's son, the emperor Qianlong.
