In Water Margin, Wu Song meets Sun Erniang at the () Hotel.

Wu Song met Sun Erniang at the Cross Slope Hotel.

Excerpt from the original text:

Three men ran across the ridge, and when they looked at it, they saw about a dozen thatched houses under the earth slope in the distance, and a wine curtain was picked out from the willows beside the stream. When Wu Song saw it, he pointed his finger and said, "There is no hotel there!" Three men ran down the hill and saw a woodcutter at the edge of the hill, picking up a load of firewood. Wu Song shouted, "Man, may I ask what the place name here is?" The woodcutter said, "This ridge is Mengzhou Road. At the edge of the big forest in front of the ridge is the famous cross slope. "
