1June, 944, in order to better deal with the postwar Japanese problem after the Pacific War, the American government entrusted ruth benedict, an assistant professor of Columbia University, to conduct a research project on Japanese society and culture, hoping to better understand Japan's national character and way of thinking. Because of the war, Benedict couldn't visit Japan in person, but by interviewing Japanese prisoners of war and Japanese-Americans, and even studying Japanese movies, videos and books, she wrote her masterpiece Chrysanthemum and Knife, which will be famous at home and abroad in the future.

Although "Chrysanthemum and Knife" was later criticized by anthropologists, it did put forward two characteristics of Japanese national character, which are very contradictory but unified: loving beauty and martial arts, being polite and aggressive, liking the new and hating the old but being stubborn, being obedient and unruly-just like chrysanthemum and knives that Japanese love. After the Meiji Restoration, Japan experienced a long history of worshipping foreign things and fawning on foreign countries, first Germany and then the United States. During this period, classical music, as the core part of western civilization, took root and sprouted in Japan. Today, Japanese pianists, violinists and conductors have gained a place in the world music scene, and the Japanese people's understanding, enthusiasm and love for classical music even far exceed the audience in many western countries.

This is also reflected in Japanese film and television dramas, no matter what theme (love through time and space, or confession of social phenomena), no matter what type (commercial film "The Thief of Keys" or literary film "Funeral Master"), no matter what category (whether it is a live-action movie, a two-dimensional animation or even an advertisement), what's more, movies are based on classical music. Interestingly, among these works with classical music scores, the Japanese people are almost obsessed with Bach. Whether romantic or cold, aesthetic or cruel, order or chaos, we can always hear the sound of Bach's music slowly in the opposition full of "chrysanthemum and knife"
