Classical Chinese annotation refers to explaining some words, phrases and sentences that are difficult to understand in the text and helping learners translate classical Chinese. The text lists the notes of ancient books, with double-line notes and annotations. The notes of modern books are listed under the current page of the text, called footnotes, also known as local notes; Those listed at the back of the article or book are called the last note.
