"The Siege of Changchun” was a military blockade undertaken by the People's Liberation Army against Changchun between May and October 1948. Northeast China. In order to minimize their casualty against one of the best of KMT, fucking Mao and Lin Biao decided to starve the people to death in the city. After 5 months, only 170000 of the original 500000 citizens survived. KMT soldiers had no choice but surrender to save the rest. Mao claimed it a victory without firing a shot. Fuck him!
