"Aga" is a kind of traditional Tibetan architectural craft for the roof or floor inside of a house. It is made from clay and crushed stones that locals call "aga soil" (a kind of highland soil) mixed with water and then laid out on the ground or on the roof, and is then repeatedly, stomped on manually to make it solid and smooth, so that no water can leak through. Groups of workers hold wooden tamps (on the bottom is a round block of stone, the top is a straight stick) to beat the aga soil, continuously singing labor songs while stomping the floor or rooftop. Singing keeps the workers’ steps in time, and the sound of the wooden tamps stomping on the ground keeps the beat; round after round of chorus, this is what it means to "stomp aga".

During the "aga" stomping process, much-needed labor groups coordinate together, and the songs can make the strenuous and mechanical physical labor easier, lively, and improves labor efficiency. It also helps the workers maintain good mental states, and reduces the amount of physical exertion. Therefore, the songs and dance that accompany the "aga" stomp has become a kind of unique cultural landscape. "Aga" stomp songs are mostly drawn from folk songs.

"Aga" and cultural preservation are closely related. The protection and preservation of Tibet’s ancient architecture has received attention for a long time. Tibet has always insisted on restoring ancient architecture to its original forms, especially during the course of preservation projects. Traditional Tibetan architectural crafts led by "Aga" has always been used in the renovation and preservation for ancient architecture's
