If you don't have a certain knowledge of ancient Chinese and basic linguistics from the beginning, you plan to read books on ancient Chinese from the beginning, which feels terrible and probably doesn't understand at all. Therefore, there are almost no "basic" textbooks in ancient Chinese books, which are generally research-oriented. Typical examples are Fang Guili's Ancient Phonology and Zheng Zhangshangfang's Ancient Phonology. Only He Jiuying's Ancient Sound is suspected to be basic. Guo Xiliang's Handbook of Ancient Chinese Characters is specially used for checking. There are many basic textbooks and textbooks for general phonology, and the pronunciation of ancient, medieval, modern and even modern parts will be involved, and it is relatively simple and easy to understand. Of course, the knowledge of ancient sounds in basic textbooks is the most basic, and it is impossible to be as in-depth as the monographs of Fang Guili and others above. Such textbooks are well written by Tang Zuofan's A Course in Phonology, and Yang Cambridge's Lectures on Chinese Phonology. The older one is Wang Li's History of Chinese (involving not only phonetics, but also some grammar words in the history of phonetics, etc. ).
