This book is a collection of calligraphic works of Mi Fu in the running script, selected from more than 200 couplets written by Mi Fu. The characters written by Mi were chosen based on clarity and were logically and artistically arranged. The collection is a good reference book for the study of Mi Fu’s calligraphic style. Some photos still need further refinement. “集字” (jizi) refers to a collection of calligraphic works of a certain calligrapher of a previous dynasty. For example, Emperor Wu of Liang ordered his minister Zhou Xingsi to compile One Thousand Characters by making rubbings of engraved calligraphic works of Wang Xizhi and to bestow a copy of this book on each of the eight princes (Xu Shi Fa Shu Ji). One Thousand Characters is the earliest jizi collection. The Preface to the Buddhist Scriptures Engraved on Stone in Wang Xizhi’s Collated Characters made by Huairen, a Buddhist monk active in the early days of the Tang Dynasty, is the earliest jizi collection engraved on stone. In modern times, Kang Youwei once said, “There are at least 18 jizi collections of Wang Xizhi.” Obviously, jizi was very popular in the field of calligraphy.
