In the morning of Sho Dun, which is also known as the festival of "Sunning of the Buddha", hundreds of lamas would carry the huge Thangka and lift it up to the hill in a snake-shaped formation. The heavy weight is laborious even for the young and strong men. Every year during the festival, a large (60 meters tall and 40 meters wide) Thangka, which is regarded as a sacred object, would be displayed at the hill outside the Drepung Monastery. Due to the gigantic size, it could only be exhibited once a year. The "Sunning of the Buddha" ceremony attracts lot of believers to worship the Buddha statue every year, signifying the official start of Sho Dun Festival.
