Chyi Chin's calligraphy and painting, in ancient times, playing the piano (mostly Guqin), playing chess (mostly Weiqi) and calligraphy and painting were the skills that literati (including some aristocratic families) must master to cultivate their self-cultivation, so they were collectively called Chyi Chin's calligraphy and painting.
