A fortune teller.

Grandma, my grandfather's mother, and my grandfather, my grandfather's father or father.

Grandma is a title of respect for female elderly people in some areas of China. Since the Qing dynasty, great-grandmother has been commonly known as grandmother. Grandfather is also used to address other people's fathers. Taigong is mostly used in southern China, especially in Guangdong, Jiangsu, Zhejiang, Jiangxi and Taiwan Province provinces, but it is rare in northern China. When you burn incense, you always pray to Taigong Taipo. When you visit a grave in Tomb-Sweeping Day, you always bow to an older grave and pray for good luck, safety and health in the future.
