A flag-raising ceremony is held at Potala Palace Square, Lhasa, capital city of China's Tibet autonomous region, to celebrate the 58th Serfs Emancipation Day on March 28, 2017. 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.
