Over the past 20 years, under the guidance of the basic principle of "peaceful reunification and one country, two systems" and through the joint efforts of compatriots on both sides of the strait, compatriots in Hong Kong and Macao and overseas Chinese, cross-strait personnel exchanges and economic and cultural exchanges have flourished. The situation of mutual promotion, complementarity and mutual benefit between the two sides of the Taiwan Strait has initially taken shape. We have reason to believe that the return of Taiwan Province Province to the embrace of the motherland is just around the corner. 1, "one country, two systems" is the development of the ideological line of emancipating the mind and seeking truth from facts. After the founding of New China, the socialist system was implemented. Socialism is a brand-new undertaking, unprecedented. In the stage of socialist exploration, especially in the "Cultural Revolution", the people of China encountered unprecedented setbacks. Under the spring breeze of the guiding ideology of "emancipating the mind and seeking truth from facts", the ten-year "Cultural Revolution" turmoil ended, and the history of China entered a new era of great reform, opening up and socialist modernization. In the new historical period, we are facing new problems and challenges. The concept of "one country, two systems" is to fill the lack of the principle of solving new contradictions in this period with new ideas, new systems and new means. 2. "One country, two systems" embodies the respect for human rights and the protection of people's interests, and is a model for realizing the principle of "humanization". "One country, two systems" ensures that the existing social and economic systems, lifestyles and customs of Taiwan Province Province, Hong Kong and Macao remain unchanged, which meets the requirements of compatriots in Hong Kong, Macao and Taiwan and is a model for respecting human rights. "One country, two systems" has realized the great cause of the reunification of the motherland, promoted economic development and cultural exchanges, and safeguarded the peace and stability of the motherland. Under the guidance of the basic policy of "peaceful reunification and one country, two systems", Hong Kong and Macao have returned to the motherland one after another, and the issue of Taiwan Province Province has also undergone a qualitative change, and the situation in the Taiwan Strait has gradually eased. At present, cross-strait exchanges and cooperation are becoming more and more frequent, showing a good development trend. We have every reason to believe that the return of Taiwan Province Province to the embrace of the motherland is not far off. The peaceful settlement of the question of Taiwan Province Province is a strong demand of the people of China who have suffered from war, and it also meets the requirement that "peace and development" become the theme of world development. 4. "One country, two systems" is a model to solve tribal conflicts and partisan disputes, and it is also a model to solve ethnic problems and achieve mutual benefit and win-win results. The implementation and development of "one country, two systems" shows great vitality, which fully shows that capitalism and socialism are not incompatible. In a country, socialism and capitalism can live in harmony, which shows that capitalism and socialism have a broader prospect of long-term existence on the same earth. Whether it is a capitalist system or a socialist system, it is a kind of activity rule between people or between people and society, and it is two different attempts of human society, and these two rules have their own strengths and complement each other. "One country, two systems" is a milestone in our understanding of the social system. This view comes from Liu De's book On Wealth.
