Notes on Shuowen Jiezi (the first volume of this set): The earliest book about Chinese characters was published by Phoenix Publishing House (formerly Jiangsu Ancient Books Publishing House) and re-punctuated by Professor Xu Weixian of Nanjing University, which is one of the complete works of Duan Yucai.
I haven't finished reading this set of books, but I've read about a third to a quarter of them. It is traditional and has standard seal script. I don't have much information So I bought other books later.
Homologous dictionary: I have read this set of books roughly, and occasionally search for related words. You can tell by the name. This is an introduction that some words are derived from some basic words. It's full of dry goods, which makes it dry to read. This paper introduces the explanations of these words in some other books.
Chinese Phonology Dictionary: This is a set of books about phonology, which can help you learn the basic knowledge about phonology. This set should be a new rhyme. The new rhyme is relatively broad, perhaps because history has changed and it is closer to the rhythm of ancient Chinese.
Synonym dictionary: I didn't read much when I bought it. I wanted to buy synonyms, but I didn't read them when I found them. However, it can still serve as a reference book.
Dictionary of simplified characters, traditional characters and variant characters: relatively small and simple in content. Mainly some writing introductions. Not all simplified characters are the result of simplification of traditional Chinese characters. At present, most of the simplified characters or characters with fewer strokes we use exist in history. Therefore, when writing China's traditional calligraphy works and works, we should pay attention to the distinction between complexity and simplicity.
Practical multi-tone dictionary: mainly depends on how many pronunciations some words have, and wants to know some ancient or dialect pronunciations from them. But unfortunately, they are all arranged according to Putonghua, and there are no ancient sounds and dialects.
