The mountain that lays giant “eggs” every 30 years

Guizhou's Chan Da Ya cliff, known as the "egg-laying mountain," mystifies with smooth, egg-shaped stones that roll down its face approximately every 30 years. This rare natural phenomenon occurs as wind and rain erode softer limestone, revealing harder, embedded stones. For the Shui people, these stones are cherished cultural treasures and lucky charms.
