 All citations of Chinese texts follow the Chinese Text Project (CTP)  (https://ctext.org/)  numbering. Note that translations of Chinese material are included in the Works Cited list where available. Translations are cited by name, CTP numbering, translator and year. While the texts here are broken into Pre-Han, Han, and Post-Han categories, for some of these texts dating is difficult and controversial. The categorization here is based on traditionally accepted dating.
