1. Zhonghua Book Company's Shuowen Jiezi (with a word check), photocopied by Tongzhi Chen Changzhi (according to Sun Xingyan's Daxu Song Edition), the original is fine, with two leaves spelling one leaf. This version is moderately thick, with a word search, which is the most convenient to use. Text font category 5, Pinyin font category 6, clear and easy to read. An old gentleman with bad eyes is a little inconvenient. 2. China Bookstore's Shuo Wen Jie Zi (no word check) photocopied the engraving of Jiaqing Tenghua Pavilion (turn to Vae edition), the original version is fine, and the leaves are not spelled. This book is of moderate thickness, easy to read, well carved and full of flavor in the Song Dynasty, but it is a bit inconvenient to use without text. 3. Zhejiang Ancient Books Publishing House "Notes on Explaining Words", photocopied "Jingyunlou" engraving (first edition), the original version is fine, with two leaves and one leaf. This version is a bit thick (too many words to do), and it is a better version at present, because there is a look-up table in the memory, and the big characters are easy to read and the small characters are too dense. I just saw the Shanghai ancient book edition, which is also a photocopy of Jingyunlou. It's 16, and the font should be larger than the Zhejiang ancient edition. It is also a good version.
The photocopied edition of Zhonghua Book Company is good, but it has been reduced, and the four editions have been reduced to one edition. Apart from this shortcoming, everything else is perfect. I have always used it as a reference book. The electronic version of the general book (Chen Changzhi's engraving) with every word numbered is the best, and it is convenient to check by number and turn pages. I use the electronic version of the primary school hall, but it is not compatible with simplified Chinese characters. Peking University Publishing House. Although the Chinese translation is a little small, I still read English (*).
