Education: Beiyang University was once as famous as Cambridge and Harvard (unfortunately, it only provides undergraduates, but it is said that its graduates can be interviewed at any international university for further study). Even during the war, the National The National SouthWest Associated University trained many first-class talents and maintained the first-class scientific research level.
Economy: Shanghai is the only financial center in Asia, and its position is far greater than that of Tokyo and Hong Kong.
Culture: Needless to say, in addition, Shanghai is the second largest film producer in the world after Hollywood, and its star (the famous Looking Back at Parliament) has fascinated millions of heroes.
Politics: steadily promoting democracy (by 1946, Chiang Kai-shek had been elected with 200 million votes and 90% support rate) and achieved great international status. He entered the United Nations as one of the four largest countries in the world. During World War II, Chiang Kai-shek served as commander-in-chief of the Far East Theater, leading the entire allied operations. The cover of Time often comes from China.
As for the popular songs for college students you mentioned, now we only know the names, not the tunes, so it is of little significance. But at that time, college students were very enthusiastic about serving the country, and they regarded the country as their own life. Chiang Kai-shek immediately recruited 200,000 college students to join the army voluntarily. I look forward to that era.
