藤原佐理的线型用笔自然不羁，洒脱而有名士风骨。由小野道风开创的 和样书风，经过佐理的探赜发挥，拓而为更加洗练简净、沉厚雄健、淋漓痛快的书风。懒散随意、率意豪放、不拘礼法的性格，在作品中则显现为奔放率性的天才气度。藤原佐理的线型书风风格强烈，他将自己的个性与扎实的功夫熔为一炉，擒纵自如而节奏自然，用笔迅捷而未曾偃卧，淋漓痛快而不失沉着，粗服乱头而不失韵致，中实的线条产生出迟速疾涩的丰富变化。藤原佐理成功地将跌宕起伏的线型用笔作为构成作品的表现性元素，在唐样书风的基础上开拓出“佐迹”和样书风的新意境。

Fujiwara Saori's linear pen is natural and uninhibited, free and easy, and has the style of a celebrity. The style of writing created by Ono Michifeng, after Saori's exploration, has been expanded into a more concise, clean, heavy, majestic, and dripping style of writing. The character of laziness and casualness, recklessness, and informality is shown in the work as an unrestrained and straightforward genius. Fujiwara Saori's linear style of writing is strong, he fuses his personality with solid kung fu, escapes freely and the rhythm is natural, the pen is swift and never recumbent, dripping with joy without losing composure, rough and messy without losing rhyme, and the lines of Zhongshi produce rich changes that are slow and astringent. Fujiwara Saori succeeded in using the ups and downs of the linear pen as an expressive element to compose the work, and opened up a new artistic conception of "Saji" and the style of the sample calligraphy on the basis of the Tang style of calligraphy.
