Mr. Zheng refers to Zheng He. (Although he gave Adam Cheng a picture, hahahahaha made me laugh for a while), Zheng He fell in love with the young mermaid grandmother when he went to the Western Ocean, and helped the mermaid family escape the killing of human beings at that time.
Perhaps in the mermaid's long life, this love is only a fleeting moment, but like the grandmother who has a beautiful fish tail with a gradient color, Shanshan will always bury this love in her heart. When she thinks of it, her eyes are gentle and her friendship is tender.
