Introduction to the Grandma Hall: In the east courtyard of the Fire God Temple, the main hall is the Grandma Hall, which is dedicated to the harem empress of the Fire God True Lord, that is, the wife of the Fire God True Lord. Because she is a miracle doctor who is good at surgical treatment and specializes in treating various pimples, she is also commonly known as the Pimple Grandma among the people. On the east side of the Grandma Hall is the Son-Song Hall, which faces east and west and is dedicated to Son-Song and Mother-Song.
