1. China is not the only one with calligraphy. Japan, South Korea, and North Korea, countries that are influenced by Chinese culture, all have calligraphy.
2. Japanese calligraphy is called calligraphy. It started from China. According to the "Nihon Shoki" records, in the 58th year of Emperor Ongami's reign, Wang Injin, the envoy of Baekje Kingdom in Korea, presented ten volumes of "The Analects of Confucius" and one volume of "The Thousand-Character Classic", which was the beginning of the spread of Chinese characters to Japan (the specific year is unknown). But even earlier than that, Chinese characters were clearly known in interactions with China. It was a man named Wang Ren who arrived in Japan and brought with him systematic Chinese characters and Chinese classics. Therefore, this can be regarded as the real beginning of Japanese people learning Chinese.
3. Calligraphy has always been closely related to painting in Korea. They believe that painting is influenced by calligraphy from the perspective of the powerful and harmonious arrangement of brushwork.
