嘉慶帝
Although he pledged to retire, and took the title of Retired Emperor after officially yielding the throne to his son (the Jiaqing Emperor) after 60 years, 124 days of rule, the Qianlong Emperor never spent a night in his Palace of Tranquil Longevity, and continued to hold on to power. The Jiaqing Emperor reigned only nominally until his father's death on 7 February 1799, making the Qianlong Emperor's actual reign 63 years and 122 days long.
