This festival is held in Chiang Rai, Thailand. It is a festival to bring together the people of the the four countries the boarder the northern part of the Mekong River;Laos, Thailand, Burma(also known as Myanmar) and China.
The festival includes foods, dancing and what would a festival be without being able to buy things. According to one blog I found you could get many different things from artisan items to fake Prada.
