One is Barkhor Street, 1000 meters long around the Jokhang Monastery. This is the central ring. The third is Linkhor Street of 5,000 meters runs around the old city of Lhasa. this is the outer ring. There are believers Kora around Nangkhor and Barkhor Streets every day, while Linkhor Street is the route for Kora in important days.

On the 15th day of the 4th Tibetan month, the Kora activity reached the peak. From 2 a.m. until the evening, the crowds flowed like stream. On this day, no matter men or women, young or old, Tibetans will dress in festive costumes and do the Kora.
