Introduction to Shuangshitou: Shuangshitou Village is located next to the ancient road in the west of Beijing. When viewed from above, the village looks like a phoenix spreading its wings. It is named after a pair of huge rocks in the ditch. The stone culture is reflected everywhere here, just like what is sung in the song: "Stone mills, stone mortars, stone walls, a room built on top of the stone, a stone gate opened to welcome guests from afar, and a bride married in a stone house."
