Is the font on this paper lowercase? What is it written in?

Hello, this is a small running script, which is a little different from lower case because it means running script. If you want to learn lowercase letters, I personally recommend Zhong Shaojing's Ling Fei Classic and Wen Zhiming's Lisao Classic. Of course, you can actually download the HD version of these two copybooks and see which one you like better, so you can choose which one. You can find this article to read the classic copybook in lower case (download the high-definition copybook picture). This paper introduces ten very classic small letter copybooks, such as Ling Fei Jing and Li Sao Jing, and their download addresses for your reference! I hope it helps you!
