Where does Japan's way of neutralization come from?

Japanese ancestors not only tried hard to learn the material civilization of the mainland, but also tried their best to learn and accept the advanced ideas and concepts of the mainland, such as Confucianism and Buddhism. After China's traditional cultural thought "the golden mean" spread to Japan, it became the "way of neutralization", emphasizing impartiality and being indifferent to elegance, and later became the aesthetic tradition of the Japanese nation. The formation of this aesthetic tradition is related to the gentle character developed by primitive Japanese ancestors who have been living in a warm natural environment, and this national character is more likely to accept China's philosophical thought of "golden mean".
