在元朝复古思潮盛行的大环境下，杨维桢的奇崛自傲尤其突出，他以狂纵、奇古的书风和独到的笔法著称，为元末书坛注入了新鲜血液。以《城南唱和诗卷》作为切入点来看，杨维桢的笔画质感坚硬且奇崛，富有力感、立体感、生命感、节奏感。同时，起笔多切笔，露锋入笔，行笔时注意绞转，转折处以提按方折为主，兼有圆转。他将晋唐楷法和汉隶、章草、今草笔法融合到一起，笔势紧密且斜倾，笔意明快鲜活、节奏潇洒，无形中抒发了纵情之情。杨维桢对于元末明初承前启后，一定程度上推动了诗文与书法的发展。而对其行草书笔法及艺术思想的深入了解，对当下的学习也颇有益处。

Under the prevailing environment of the trend of retro thoughts in the Yuan Dynasty, Yang Weizheng's extraordinary pride was particularly outstanding. He was famous for wild style and unique writing techniques, which injected fresh blood into the calligraphy circle at the end of the Yuan Dynasty. From the point of view of Song and Poems in the South of the City, Yang Weizen's strokes are hard and strange, with a sense of power, dimension, life and rhythm. At the same time,he combined the regular style of the Jin and Tang Dynasties with the writing style of the Han Li, Zhang Cao and Jin Cao. The style of the writing was close and inclined, which virtually expressed the indulgent feeling. Yang Weizhen's contribution to the late Yuan Dynasty and early Ming Dynasty promoted the development of poetry and calligraphy to a certain extent. A deep understanding of his cursive writing techniques and artistic thoughts will be of great benefit to our current study.
