Introduction to Hangu Feihong: Passing the west cliff to between the two peaks is the modern building "Hangu Feihong". It is a steel-framed overpass spanning a deep valley. This bridge is the only passage between Wudang Peak and Jiangjun Peak. The bridge is 50 meters long and 2.3 meters wide, with mesh-type steel guardrails on both sides, arched, like a rainbow in the sky.
