Tibetan floor ramming

"Da-a-ga" is a traditional floor making method in Tibet when building or renovating a house.

Tibetans combine a mixture of small stones, earth and water on the floor and keep ramming it to make the floor firm.

It's usually conducted by two groups of people. Each person has a stick with a flat stone tied at the end and keeps stepping and ramming the floor about 1 square meter around him or her. It normally takes around a week to finish ramming a plot of floor until it is firm enough.

Often with people singing Tibetan folk songs while ramming the floor, the project takes on the look of a group dancing.
