Licensed materials · 各類內容的許可
Everything on this site falls into one of three buckets. Each has its own terms:
| Material | Licence | Commercial use? |
|---|---|---|
| Original classical texts (public-domain Chinese source) | Public domain | Yes - with attribution |
| The library's own translations, glossary, and bilingual corpus | CC BY-SA 4.0 | Yes - but derivatives must stay open |
| Tool scripts / code | MIT | Yes |
See the full contributor terms, including what may and may not be charged for, on the Contributor Agreement page.
The short version of CC BY-SA 4.0 · 簡述
CC BY-SA 4.0 (Attribution - ShareAlike) lets anyone share and adapt the licensed material for any purpose - including commercial use - on two conditions:
- BY - Give credit. You must attribute the source in a reasonable way: title, the library, the licence link, and a note if you changed it.
- SA - Share alike. If you remix, transform, or build on the material, you must publish your contribution under the same licence - CC BY-SA 4.0.
The authoritative legal text: creativecommons.org/licenses/by-sa/4.0.
What this means for the library · 意義
- The classical texts themselves are public domain. They are the historical record; the library only arranges and annotates them. The original Chinese stays free for everyone, forever.
- Our translations are deliberately open. Every translation, glossary entry, and corpus line is CC BY-SA 4.0 - so no contributor's work can ever be locked into a proprietary product. This is the structural guarantee behind the Contributor Agreement.
- The ShareAlike clause is the trust mechanism. Any derivative work built on the corpus must keep the underlying material open under the same license. The open classical corpus itself can never be privatized or locked away.
- We translate from the classical originals. The library does not quote modern copyrighted translations (for example Legge or Wilhelm). Our English is made directly from the public-domain source text.

Public-domain source policy · 公版來源
- Source texts are taken from public-domain editions - primarily the Chinese Text Project (ctext.org) and Wikisource - and the edition is cited on each page.
- The verification date is the date a passage was checked against the source edition.
- If you believe a passage we quote is not public domain, tell us on the About page's contact channel - we will correct or remove it.
