Photo taken on March 27 shows that art performance was held in Medrogungkar County, Lhasa of southwest China's Tibet Autonomous Region, to celebrate the 59th Serfs' Emancipation Day. The annual Serfs' Emancipation Day is held to commemorate the 1959 democratic reform in Tibet, which ended feudal serfdom and freed about one million Tibetan serfs. [Photo/Tenzin]
