Who are the grandmothers, brothers carrying water, delivering medicines and Mrs. Bai who are enshrined in Tianjin Tianhou Palace?

Among many immortals, only Grandma Wang San is a fairy, which is unheard of. After the tour guide's explanation, it turned out that Grandma Wang San was from Xianghe County, JD.COM during Jiaqing period of Qing Dynasty. She is not only skilled in medicine, but also often treats people for free.
