Because China is the only country in the world where calligraphy has its inevitable historical origin, China, as one of the four ancient countries in the world, has hieroglyphics as the basis of its artistic system. Hieroglyphs have a reasonable aesthetic anatomy.

China's hieroglyphics can be preserved on the basis of the closed history of China and the expansion of dynasties, while the inheritance and innovation of history and culture and the changes of political situation. From seal script to regular script today, it is an inevitable product.
Chinese characters are characterized by changeable glyphs and strokes, changeable structures and mysterious rules, which are incomparable to Korean calligraphy. The monotonous brushwork and structure of Korean is based on practicality, which is why we should ask why the later Japanese and Korean calligraphy can't reach a high artistic level even if it is written in its own words.
