The style of this book is between official script and official script, and official script is also called "Eight Points". Therefore, Zheng Xie called his non-official script "six-and-a-half-written". The unique style of Zheng Banqiao's new book initiated the history of calligraphy. Zheng Xie's poetry and calligraphy were excellent, and he was called "Three Musts" at that time. His calligraphy is sui generis, which he dubbed "six and a half books". He also explained: "Banqiao has neither the power to pull out the rich nor the slippery snow." It's strange, and it's a way for real officials to relate to each other, but it's mixed with grass. " Judging from his calligraphy works, the so-called "method of combining real officials" actually means that officials participate in running script and write in cursive script at the same time. As for which "six points", which "half points" and where the remaining "three and a half points" are, we can't insist.
