First, the New Culture Movement took place in the early 20th century, which had a great impact on the old culture in mainland China. Taiwan Province Province was a Japanese colony.
Second, from 65438 to 0949, a large number of domestic intellectuals retreated to Taiwan Province Province with the Kuomintang, which brought traditional cultural orthodoxy to Taiwan Province Province. Now that there are two Tsinghua on both sides of the strait, don't think that Tsinghua's orthodoxy belongs to the mainland. Tsinghua in mainland China has degenerated into a university of science and engineering, and its orthodoxy is in Taiwan Province Province. . .
Third, the mainland experienced the Cultural Revolution, and many ancient books and traditional customs were destroyed in the process of "breaking the capitalism";
Fourthly, economic globalization has brought about a fierce impact of western culture on China's traditional culture, which has affected both the mainland and Taiwan Province Province. Therefore, the two sides of the strait have begun to gradually converge in all aspects, and the narrowing of this difference also indicates that the two sides will definitely move towards a unified future.
I hope you are satisfied with my answer.
