国殇 (Martyrs of the Nation / guóshāng) was a documentary TV series broadcasted by the Hong Kong-based Sun TV in September 2010. It chronicled the Second Sino-Japanese War (1937-1945), with particular focus on the role that the Koumintang (KMT)—the Nationalist Party led by Chiang Kai-shek that ruled over China during the War—played in defeating the Japanese.
Why it is blocked: Before the beginning of the Second Sino-Japanese War, the KMT waged a ruthless campaign to wipe out the Communists. However, when confronted with the Japanese invasion, the two sides mutually decided (due partially to patriotism, due partially to the Communists kidnapping Chiang Kai-shek and forcing him to end his purge of the Communists) to form an alliance. After the defeat of the Japanese, the two sides resumed their civil war, with the Communists eventually winning in 1949 and the KMT fleeing to Taiwan.
Though the KMT suffered 3 million casualties during the Second Sino-Japanese War (the numerically smaller Communists suffered roughly 500,000) and spearheaded many of the major battles, the KMT’s role in the victory has been relegated to a secondary position or intentionally overlooked in modern mainland historical narratives and textbooks. A September 3, 2010 People’s Daily editorial wrote:
The victory in the War of Resistance to Japan gives an eloquent proof that CPC is the force at the core that has saved the Chinese nation from subjugation and realized the nationwide liberation.
Thus, a film like Martyrs of the Nation which questions the notion that it was the Communist Party that chiefly led China to victory would undoubtedly be looked upon unkindly by the mainland government, which of course is led almost exclusively by the CCP. (Even though nominal opposition parties, including a form of the KMT, technically exist, they hold no real power.)
The PRC had already blocked Sun TV’s right to broadcast to the mainland in 2009, so the series was only available to mainland viewers via DVDs or online. All 40 episodes are available for free on Sun TV’s YouTube channel.
