Is there really a Princess Zhu Huan in history?

There really is such a folk version of Princess Pearl in history. This folk princess is not the illegitimate daughter of Emperor Qianlong. She is just an adopted daughter. She came to Jiangnan when she was traveling incognito. He traveled with the Prime Minister to the south of the Yangtze River, choosing places with few people. Who knows that they forget the time when they walk, and it will be dark in the blink of an eye, but they dare not find a place to eat and rest casually, for fear of encountering robbers and having no bodyguards around them. Then they decided to find a family for the night. This family has an old father and a daughter. Father and daughter are very kind and treat them warmly. Ganlong is very grateful to this family. Seeing that the old man's daughter is also very smart, she decided to accept it as an adopted daughter. He gave the old man a handkerchief and told them that if they had any difficulties in the future, they could look for the Huang Family Courtyard.
