床母 chhn̂g-bó A bed deity in Taiwanese folk religion, who protects children and ensures they grow up safely.
Found this in Li Ang’s 《路邊甘蔗眾人啃》 (Everybody nibbles on the sugar cane at the side of the road), the context is below:
Chen Junying would say this kind of thing from time to time:
“When I was little I heard about the bed deity, with people saying that it was a god.” He recovered his normal composure: “It was great, even the bed I slept in had a god, I always felt that someone was holding me while I slept, I felt really safe, like someone was looking after me.”
Quick update: the book is as sexually explicit as the 18+ label suggests.
