The Dictionary of Common Words in Ancient Chinese is the first authoritative dictionary of ancient Chinese written with the viewpoints and methods of modern linguistics and lexicography after the founding of New China. Because most of the authors are famous linguists and teachers from the front line of ancient Chinese teaching, dictionary arrangement meets the needs of ancient Chinese learners. Its interpretation is authoritative, pronunciation is accurate, examples are accurate, difficult examples are accompanied by notes and cross talk, and there are "attention" and "analysis" to prompt and analyze difficult words.
In addition to high school, in the long run, I recommend the Dictionary of Common Words in Ancient Chinese.
