Consort Yu
Also known as "5th Prince" (五阿哥; Wu Ah Ge), Yongqi is Qianlong's fifth son. His mother, Consort Yu, died of illness during his childhood, thus he was raised primarily by Consort Ling. Yongqi is Qianlong's favourite son, being intelligent, considerate, strong, and skilled at martial arts- and the most-likely heir to the throne. His all-round talents also inspire the jealousy of the empress, who hopes her son, the twelfth prince, will succeed Qianlong instead. Yongqi is close friends with the sons of Fu Lun: Fu Erkang and Fu Ertai. He and Ertai are also classmates; both study with Ji Xiaolan.
