Unsatisfied with the geomancy of the Eastern Qing Tombs, Emperor Yongzheng built the Tailing Tomb at the foot of the Taining Mountain in Yixian County. From then on, the imperial tombs of the Qing Dynasty comprise the Eastern and Western Qing Tombs. By choosing another burial ground, Emperor Yongzheng changed the funeral system in which a man and his male posterity are buried in one burial ground, making the Eastern Qing Tombs possibly fall into disuse, and setting a bad precedent for succeeding Qing emperors to choose their different burial grounds. Emperor Qianlong was the first emperor facing this question. After deliberation, in 1742, the seventh year of the Qianlong reign, Emperor Qianlong finally decided that his tomb be built in the Shengshui Valley of the Eastern Qing Tombs. To take into account both the Eastern and Western Qing Tombs, Emperor Qianlong established the zhao-mu system for the arrangement of emperors’ tombs, which was followed by succeeding emperors.
