How old is Emperor Qianlong (1711-1799) in Book And Sword and FFOSM? According to Book and Sword 2008 with Adam Cheng as the Emperor Qianlong, Heshen (1750-1799) is one of his important officers. Heshen started to work in the palace as a imperial guard in 1772. Therefore, Book and Sword took place after 1772 so Qianlong is older than 61 year old. FFOSM took place after Book and Sword. Hu Fei wasn't even born in Book and Sword. Does it mean Qianlong was a very old man at the end of FFOSM when Hu Fei was over 20 year old?
