Wiki says: JINSHA = River of Golden Sands
JINSHA = Ancient Chinese archeological site
JIN SHA = Hotel ion Shanghai
JIN SHA = very attractive chinese female actress born 14.03.83
DUNHUANG = County level city in NW Gansu province, a major stop on the ancient Silk Road route, also know sometimes as "City of Sands
