In Vietnam's Lao Cai province, it's a local tradition to climb upon this huge see-saw and ride it.

Crowds watch on as these two women are seen to be enjoying their ride on the towering see-saw, being lifted several feet up in the air.

During the rice planting festival, people will attempt to ride the see-saw to as high as it goes. Locals believe that the higher the see-saw the better the crop yield will be.
