BEIJING, March 27 (Xinhua) -- A two-part documentary to commemorate the 57th anniversary of the emancipation of Tibetan serfs was aired by China Central Television (CCTV) over the weekend.

The documentary features archive footage of the 1959 democratic reform of Tibet, which freed about 1 million Tibetans from slavery, and interviews with those who experienced and witnessed the reform, as well as Chinese and foreign scholars.

The documentary, broadcast on Friday and Saturday, recounts the origins of Tibetan serfdom, the significance of ending it and development in the autonomous region ever since.

The documentary will be rebroadcast on Monday, the day designated by the authorities in 2009 to commemorate the abolition of serfdom.
