|Date of Birth:||September 16, 1782|
In 1806, Prince Mianning, the eldest of the Jiaqing Emperor's three sons, was about twenty years old. He was known as the Crown Prince of China and the heir apparent to the imperial throne. He was companion to a male Celestial dragon, Lung Tien Chuan, who was Temeraire's twin brother.
Temeraire and William Laurence exposed and blocked an attempted coup by the emperor's brother Prince Yongxing, who hoped to place Mianning's younger brother Prince Miankai on the throne and take control as imperial regent.
Deviations from history
Historically, Mianning was the second-born and only surviving son of the Jiaqing Emperor and his first consort, Hitara (posthumously, the Empress Xiao Shu Rui); their first-born son, Prince Mianmu, died in infancy.
The Jiaqing Emperor died without naming a successor. His widow, Niuhuru (Empress Xiao He Rui), used her authority as dowager empress to name her stepson the next emperor, bypassing her own two sons Miankai and Mianxin.
