The ancient city of Dukezong in Shangri-La, Tibetan means Moonlight City, also known as a castle built on stones. Entering the ancient city is first a small square, where locals often dance in ethnic costumes. There are also three or three tourists feeding pigeons. Walking up the steps, you can see the big prayer wheel. Many devout believers push the prayer wheel around three times clockwise and make their own good wishes. Dukezong Ancient City is really a place worth going again.
