Why is it impossible for Master Gan Long to know Xia Yuhe by Daming Lake?

According to the story of the princess, Emperor Qianlong fell in love with Xia when he visited Daming Lake in Jinan. Eighteen years later, Xia and the daughter of Emperor Qianlong went to Beijing to find their relatives. As a result, she was mistakenly replaced by a swallow and entered the palace. This is the basis of the whole story of Princess Zhu Huan.

After two strange experiences and heartbreaking confessions in Princess Zhu Huan, Wei Zi and Emperor Qianlong recognized each other, and she and Swallow also had lovers, and finally reconciled with the biggest enemy in the palace, Queen Ulannara. However, in the third film, when Emperor Qianlong made a southern tour, the queen interrupted her family, and a lot of troubles were born.

According to historical records, the queen's hair loss should occur during the fourth southern tour in the thirty years of Qianlong. In the play, Wei Zi had already given birth to a child before this southern tour. Combined with the plots of the first two films, it can be speculated that Wei Zi officially entered the palace at least four to five years before Qianlong's four southern tours, that is, more than twenty years ago.

However, according to reliable historical records, the only time Emperor Qianlong visited Jinan in his life was during his thirteen-year eastern tour, and it was at this time that he met Xia. However, it was only seventeen years from the thirteenth year of Qianlong to the fourth time in the thirty years of Qianlong. If you count one or two TV series, it will be less than ten years.

Generally speaking, according to the historical records about Ganlong's patrol, Ganlong had no time to know Xia at all. As far as time is concerned, the whole story of Princess Zhu Huan is impossible.
