At night they ate in the inn. When the dishes were brought up, Wang Da, Lao Wang’s son, asked how much a plate of stir-fried greens cost. Several tens of copper coins—so shocking he could barely sit still.
The attendant laughed: "Our inn is small and in a remote spot, so this counts as cheap. If you stayed somewhere like Tongfu Inn, a plate of greens could cost you this much."
The waiter held up four fingers.
Four hundred copper coins.
"Th-then would anyone eat it?"
