What are the characteristics of Song Ke's cursive script?

Song Ke's cursive script is a unique style of mixing Cao Zhang with weeds, which can be said to be the most important stop on the road of calligraphy innovation in the early Ming Dynasty. His cursive script was deeply influenced by Kang Shan. However, compared with Kang Richi, he can not only completely integrate the brushwork and structure of Wild Grass, but also make his brushwork more colorful and magnificent, which fully shows Song Xin's extraordinary artistic creativity. Masterpieces of cursive script that have been handed down to this day include Du Fu's Zhuang You Shi and Jin Xue's Pian Juan.
