The fountain pen copybook of Ling Fei Sutra is "Ling Fei Sutra's Brushwork and Its Characteristics" published by Xiling Seal Society. The pen copy of the copy has an analysis of the brushwork and the original copy. (It is sold on a certain treasure, go and buy it directly)
I bought "Tang Xiaokai Lingfei Jing" and "Lingfei Jing Brushwork and Its Characteristics". Comparing the original post and the copy of the post, I can find that compared with the original post, the calligraphy of the post post is very similar, but there is no difference between the original post and the original post. The characters are beautiful.
