In February of the first year of Jiaqing, Fu Kang 'an was awarded a Beizi and died in May of the same year.

2. Fu Erkang:

Fu Erkang's identity in the play is the imperial bodyguard, Xia Ziwei's husband, the imperial edict of Emperor Qianlong, Fu's parents' son, and Fu Jidong's father. Its historical prototype is Heshuo, Princess Xu of Jiajia and Fu Longan, the son of Fu Heng.

Fu Kangan's story:

Notes on Nanting recorded that Fu Kang 'an led troops to the Western Expedition and passed a temple. At this time, the sun was setting, and he camped in this temple. At night, frogs kept barking, and Fu Kang 'an couldn't sleep. He was very angry and ordered the soldiers to go out and drive away all these frogs.

The soldier caught one and gave it to Fu Kang 'an. Fu saw that the frog was green and lovely, so he lit a little on the frog's forehead with a brush and then released it. Since then, the frogs in this place have a red dot on their foreheads, which has existed until today. It is said that keeping this frog at home can avoid fire, so local residents call it "frog".
