A pass before a village Taoping began as a mountain pass on the road from the Chengdu plain into the highlands. In 111 BCE the Western Han set up a county seat, Guangrou, at the site. The village grew around the pass, and its form follows defence rather than display: narrow lanes, blind corners, connected roofs and a single tower that can see the approach. The Qiang population is 98 percent of the town's residents, and the old village is still a place where people keep stores and animals.

Water below the stone The underground water network is the part visitors most often miss. Channels run beneath the lanes, fed from the mountain streams, and can be reached through stone openings. In a siege, the village could draw water without going outside. The system also supplies everyday use and helps drain the site. It is not a mysterious lost technology: it is a practical answer to a dry, defended slope, maintained by the households that use it.

The tower and the roofscape The watchtower rises above the village with a slightly curved, fish-back profile. Its walls taper upward, and its windows are small. Around it, flat roofs are used for drying grain and for moving between houses without entering the lane. The village was rated a 4A scenic area in 2013, and tourism now supports many households. The risk is that the lanes become a stage; the test is whether the water channels, roofs and fields remain in use.
