In ancient China, there was a saying of "Qin, Qi, Calligraphy and Painting". What does Qin mean?

Chyi Chin refers to the seven strings in Chyi Chin's paintings and calligraphy. In the long historical stage of ancient China society, "Chyi Chin, chess, calligraphy and painting" has always been regarded as the only way for literati to cultivate themselves. Guqin, because of its beautiful, harmonious, light and elegant musical character, embodies the arrogant and extraordinary attitude of literati, especially in music, chess, calligraphy and painting.
