"This is a modern history of China, a story of the Chinese people's defense of national independence and unity against foreign aggression, in which many people and events played a decisive role in the development of Chinese history, had a huge impact on Chinese history, and contributed to the formation of the Chinese Anti-Japanese National United Front - the Xi'an Incident.
When the Japanese imperialists occupied the Northeast, Chiang Kai-shek did not resist the Japanese invaders and ignored the anti-Japanese sentiments of the Chinese people. Instead, he implemented the policy of "Anti-foreign forces must first pacify the interior" and carried out six large-scale encirclement and suppression campaigns against the Red Army.
Zhang Xueliang advised Chiang Kai-shek several times to abandon the civil war and unite against Japan, but Chiang Kai-shek refused to listen. Zhang Xueliang saw that Japanese imperialism was gradually eroding our land of China. Unable to bear it, Zhang Xueliang and Yang Hucheng carried out "military remonstrance" against Chiang Kai-shek on December 12, 1936. They detained more than a dozen important military and political officials and informed the whole country that they proposed eight proposals, including reorganizing the Nanjing government, ending the civil war and uniting to resist Japan, releasing all political prisoners across the country, and convening a parliamentary conference. This was the Xi'an Incident that shocked China and foreign countries. "
