Plastic Japan investigates the origin of Japanese pop culture, which is used to pro-Japanese people, but it doesn't know why. Take his analysis of Japanese "Kawii culture" as an example. He pointed out that "Kawii" is not the same as Chinese cuteness and English cuteness, and its meaning is far broader than both. Tracing back to the source, the pillow in Tang and Zhao dynasties is attributed to pillow grass, and its towering architecture attracts attention. In Pillow Grass, Qing once wrote that "small things are lovely". In Lovely Things, he wrote: "A child about three years old got up in a hurry, and there was a tiny dust on the road. He found it carefully. He picked it up with his cute little finger and showed it to adults. It is really cute. When Misha's hair covers their eyes, children with this kind of hair will not brush it away. It's also cute to look at things with your head slightly sideways. " Tang came to the conclusion that Japanese traditional aesthetics has included the consciousness of "home" in later generations. Subsequently, he convincingly outlined the invincible track of "Kwai Yi" aesthetics in today's pop culture field from many phenomena, such as Girl Puppet by Taizaitai, Family Game by Mori Xiguang, Japanese animation, Seiko Matsuda and PrintClub.
