Writing and character shapes

Hanzi Writer by David Chanin (MIT) powers handwriting practice. Stroke data is from Hanzi Writer Data, derived from Make Me a Hanzi and fonts by Arphic Technology. The unmodified data is redistributed under the Arphic Public License.

Component data derives from 開放詞典’s Chaizi dictionary (2015), CC BY 3.0. We select simplified components and add teaching notes; these are learning aids rather than a complete history of each character. Original attribution.

Lessons and audio

Modern stories, translations and teaching notes are AI-assisted editorial pilot materials. Classic quotations are presented separately from modern explanations. Narration is generated locally with Melo TTS (Chinese) and Supertonic 3 (English). Recordings have not been professionally reviewed in full.

Learning guide and course sequence. Idiom sources were checked against the Ministry of Education Dictionary of Chinese Idioms; poem texts and readings against Hong Kong Education Bureau reading resources. Individual lessons retain their source links and identify excerpts or teaching adaptations.

Practice levels

Starter, Developing and Confident are editorial practice groups, not official school grades. HSK 3.0 labels are a partial index of existing content, not a complete syllabus.
