What is piano, chess, calligraphy and painting? Especially this chess character, is it Go or Chess?

"Qin" refers to guqin. Before the Han dynasty, it was a banjo, and it was five tones for the "Gong Shang Jiao Zheng Yin", so there is an idiom "Five Tones Incomplete" to describe a person's bad voice. Later, it evolved into a seven-string, seven-tone "palace edge-up-angle-positive-edge positive-royal". Qin and Qin are the most primitive traditional musical instruments of the Chinese nation, with many strings and complicated tones. Qin is regarded as the king of musical instruments of the Chinese nation. In the Spring and Autumn Period, there was a story about "Yu Boya thanked his bosom friend and broke the piano". In the Tang dynasty, there was a poem that "it is difficult to learn knowledge since ancient times because of the cold tone on the lyre".

"chess" refers to go, which was called "chess" in ancient times. Playing Go is called "playing chess" and "playing chess". The chess pieces are divided into black and white, and the rules are simple and endless, which embodies the distinct essence of China's cultural thought. The documents in the Spring and Autumn Period recorded the primitive culture of the Chinese nation. However, chess appeared late, and the setting of chess pieces was complicated, unlike the primitive culture of China.

"Book" refers to calligraphy. In the early days of Chinese civilization, there were Oracle Bone Inscriptions and inscriptions on bronzes. In the pre-Qin period, it was mainly carved on bamboo slips with a knife, with characters such as seal script and lower case. After the Han Dynasty, brush writing was the main writing style, including official script, regular script, running script, cursive script, song style and other writing forms.

"Painting" refers to Chinese painting, which is usually painted on Xuan paper with a brush dipped in water-soluble pigments. It mainly depicts landscapes, utensils, flowers and birds, and people, with simple and bright colors and freehand brushwork.
