Mind‑blowing ancient hack! 🐢 Back in old‑time Ruijin, Jiangxi, people kept turtles inside hidden drainage tunnels. As turtles crawl around, they shift sediment and keep the whole drainage system unblocked. Brilliant harmony between architecture and wildlife. This is the amazing ecological wisdom of ancient China.
