This textbook contains material for students of Classical Chinese at 3 different levels: 1) The first chapter of Mencius, reproduced from a modern punctuated edition, with very detailed notes and glosses intended for students in their second semester of Classical Chinese. 2) The same chapter, reproduced from a Song wood-block edition, which beginning students who are more ambitious may wish to use instead of the punctuated edition. 3) Notes and glosses on the Eastern Han commentary of Zhao Qi (included in the Song edition), intended for more advanced students.
