Bayon 2011April12 Cultural Heritage_ Ayai By Meu Meurn and Sin Sophear 

Ayai was performed by Meu Meurn and Sin Sophear.: The first Serey is at the face, the second one is at the chest, and the last one is at your feet.
In order to deserve the three Sereys for your own happiness, first you need to wash your face in the morning, wash your chest in the afternoon, and then wash your feet before your bed time everyday.
