Internal reasons:

1.1945-1949 In China, the main contradiction is class contradiction, especially the contradiction between landlords and peasants around the land issue. The fundamental problem of Chiang Kai-shek's loss of the mainland is that the relationship between landlords and peasants has not been resolved. After the Kuomintang retreated to Taiwan Province Province on 1949, its whole party was up and down. The Kuomintang carried out drastic reforms on the island, mainly aimed at the land issue. The Kuomintang government adopted the policy of land redemption and distributed the land to farmers, which basically stabilized the situation on the island. Therefore, after the 1950s and 1960s, the contradiction on the island is no longer the contradiction between landlords and peasants, which is also the fundamental reason why Mao Zedong basically gave up military reunification of Taiwan Province Province after the August 23rd Artillery War.

2. 1949 The economic strength and military strength of the mainland have been exhausted after eight years of anti-Japanese war and three years of civil war. After the founding of the People's Republic of China, the Korean War was fought, and then the contradiction with the Soviet Union intensified. Being in a state of preparing for war for a long time, it is impossible to effectively build the economy. It was not until the relaxation of international relations and the reform and opening up in the 1980 s that the comprehensive national strength rose.

External reasons:

1945 After the end of World War II, the world entered the Cold War between East and West. Based on its own interests, the United States changed its China policy from 1948- 1949 to vigorously support the Kuomintang government, hoping that it would become the base for Asia to contain China and the Soviet Union after Japan. Especially after the Korean War, the United States got to know China again. Pay more attention to the strategic position of Taiwan Province Province. Even after the normalization of Sino-US relations in 1972 and the establishment of diplomatic relations between China and the United States in 1979, China still maintained close relations with the authorities of Taiwan Province Province in an unofficial way.

Summary:

The background of the problem in Taiwan Province Province is complicated, and there are many reasons. There are both domestic contradictions and international environment. However, Taiwan Province Province is an inalienable part of China, which cannot be changed. Now, the contradiction of Taiwan Province Province is not the struggle between one country and two regimes, but the contradiction between reunification and Taiwan independence. A-bian's daring to trigger the fuse of Taiwan independence will surely push him back to the opposite of the people of China, and he will also fail.
