@trip.com: An entire community once lived inside this cliff 🏔️ Over 1,000 years ago, someone carved rooms, staircases and stone beds straight into the rock face at Guyaju ⛏️ Today all 100+ caves sit empty, and no one knows who built them 🕳️ Under two hours from central Beijing — would you climb up? 📍 Guyaju, Beijing, China *Disclaimer: The history in this video is based on publicly available sources and local interpretations. Guyaju's origins are still debated by archaeologists and the figures and theories mentioned are for reference only. Cr: kiantye #ChinaTravel #China #beijing #chinatrip #tripcom
