No ocean needed rice terraces become natural surfing playground

This is not ocean surfing, but something happening in rice terraces. The person is gliding across shallow water in a rice field, using the slope and water flow to create a surfing-like movement. The layered terraces, originally designed for irrigation, naturally form a water slide. The key to this activity is the balance between water depth and slope. Too shallow and it stops, too deep and it loses speed. A thin layer of flowing water on a gentle slope creates the perfect sliding condition.
