The first pair belongs to the running script. Yan Zhenqing and Miffy's style, Yan Zhenqing's style is vigorous. Mifei's painting style is peculiar in shape and full and sharp in brushwork. From the first stroke of the word "Qu", we can see the style of Yan Ti. "Five" and "Valley" are both evolved from Mi Fei's fonts, and some calligraphers' own divisions are added, while "Odd" is injected with their styles. Strange shape and vigorous brushwork.

The second pair is official script, but it is mixed with some colorful styles. Why do you say that? Because official script is famous for its slender strokes, and this pair of words is very atmospheric with solid and powerful strokes. It can be seen that calligraphers have a deeper understanding of Yan style.

These two words are both written with a brush. As for species, it is not easy to distinguish. Brush can be roughly divided into hard brush, soft brush and double brush.
