Which film and television work is the closest to the real Qianlong emperor in history?

The story of Nie Yuan in Yan Xi Palace, because in "The Royal Love in Wallace Huo Palace", the real historical Queen Nora, Gan Long doesn't like him very much, and Princess Zhu Huan, the swallow in the play, is totally fake. There is no such thing as a real swallow, and I haven't seen any other TV series about Gan Long.
