Because Democratic Progressive Party is a political party that adheres to the "Taiwan independence" line, after taking office, he not only mastered the administrative and legislative power of Taiwan Province Province, but also controlled the military and intelligence departments of Taiwan Province Province, mastered the mainstream media and educational institutions of Taiwan Province Province, and constantly promoted the measures of "de-China".

At present, not only the official and semi-official contacts between the two sides of the Taiwan Strait have been interrupted, but also people-to-people exchanges have been restricted, and even China culture has been excluded from Taiwan Province Province. Now cross-strait relations are actually in a "cold confrontation" situation, and the two sides are gradually drifting away.

2. Pro-independence forces in Democratic Progressive Party want to speed up the pace of "Taiwan independence". The future cross-strait relations will not rule out fierce confrontation.

After Tsai Ing-Wen came to power, in order to stabilize the political power and seek re-election, under the guise of "maintaining the status quo" in cross-strait relations, she gradually promoted "de-China" on the island of Taiwan Province Province. In essence, "de-China" means slowly promoting "Taiwan Province Province of the Republic of China", which is a gradual "Taiwan independence". Therefore, although Tsai Ing-Wen and Chen Shui-bian have different strategies, their goal is "Taiwan independence".

3. The public opinion of Taiwan Province Province, especially that of the younger generation, is still developing in a direction that is not conducive to reunification.

At present, a prominent social problem in Taiwan Province Province is that compatriots in Taiwan Province Province, especially young people, are increasingly deviating from their national identity. Due to the long-term anti-* * propaganda and education conducted by the Kuomintang authorities in the past, compatriots in Taiwan Province Province have developed fear, vigilance and distrust of the mainland.

Over the past 20 years, Lee Teng-hui, Chen Shui-bian and Tsai Ing-wen have spared no effort to attack, slander and vilify the "lack of democracy and freedom" in the mainland, and instilled a sense of "Taiwan independence" by revising textbooks, which has made compatriots in Taiwan Province Province, especially the younger generation, always have doubts, fears and even opposing feelings about the mainland, reunification and one country, two systems, and the younger generation's sense of the Chinese nation and greater China complex has become increasingly weak.

4. The United States initiated trade friction with China and played the "Taiwan Province Province" card, which made it more difficult to improve cross-strait relations.

After Trump was elected president of the United States, he began to implement a tough containment strategy against China. While waging a trade war and a scientific and technological war against China, it played the card of Taiwan Province Province and passed a law in Congress that seriously interfered with the issue of Taiwan Province Province, openly challenging China's bottom line and attempting to use the issues of Taiwan Province Province and Hong Kong to increase China's pressure to deal with the frontal battlefield.
