How about Ma Yongan's horse calligraphy?

just read it, it seems to be very distinctive, but it has entered a stylized thing, developing in the direction of artistic calligraphy. Strictly speaking, although writing with a brush, it is not quite in the category of calligraphy. Calligraphy talks about artistic techniques such as artistic conception and change, size, shade, length, reality and contrast, while Ma's calligraphy is more standardized and the brushwork is relatively solidified, so it can be done occasionally.
