Grandma meets the Wuchang: 20th century encounters with the Impermanence Ghost

A narrator from China recounts the tales told by their two grandmothers about a time long before they became grandmothers:

Part 1: "Paternal Grandma was fierce. No one in the village dared to cross her. She had no fear of walking in the night..." 

Part 2: Maternal Grandma and her parents had a strange experience on the same night that Paternal Grandma saw the Impermanence Ghost.
