Ancient Roofs That Last 1000 Years! 🏯 #AncientTech #TimelessCraft

"How Ancient Roofs Defy Centuries! 🏯 TimelessCraftsmanship AncientEngineering"

Summary
This video reveals two core secrets of China’s immortal wooden architecture:
1. Mortise-Tenon Mastery – Artisans hand-carve interlocking joints without nails, creating self-supporting roofs through precision woodworking passed down for generations.
2. Tile-Laying Science – Workers layer orange tiles with calculated overlaps and mud ratios, forming a 100-year waterproof shield that outlasts modern concrete.

Why It Matters
- Structural Intelligence – The榫卯 (sunmao) system allows buildings to flex during earthquakes, proven by 1,300-year-old pagodas surviving seismic zones.
- Material Alchemy – Roof tiles baked at 1,100°C develop iron-rich surfaces that shed rainwater while resisting frost cracks.
- Zero-Waste Wisdom – Broken tiles get crushed into new mortar – a circular economy practice centuries before the term existed.

This isn’t just nostalgia – it’s architectural DNA that inspired modern modular design and disaster-resistant engineering. 🔨 Every hammer strike echoes both heritage and hydrodynamics.
