The 59th anniversary of Serfs' Emancipation Day was celebrated on Wednesday in Lhasa, Tibet autonomous region. Serfs' Emancipation Day was established on March 28 by the regional legislature in 2009 to mark the start of Tibetan democracy, which ended the feudal serf system in 1959, freeing one million serfs, or 90 percent of the region's population at that time.
