Hanzi Garden is a Chinese-language learning resource that combines a dictionary, reading tools, vocabulary lists, and writing practice. Its dictionary contains more than 125,000 entries searchable in English, pinyin, or Chinese characters. Entries include simplified and traditional forms, Mandarin and Cantonese readings, stroke-order animations, and example sentences.

Learners can paste Chinese text into the reader to view per-word readings and access dictionary lookups. The site organizes vocabulary in the official study order for HSK 3.0 levels 1–9 and all seven TOCFL bands, and offers spaced repetition to support review. Users can collect words in their browser and print tianzige or mizige practice sheets, with stroke-order guides for writing.

Hanzi Garden also features 5,000 four-character idioms with translations, classical Tang-dynasty poems presented with pinyin, zhuyin, and both character scripts, and content about Chinese recipes, festivals, and regional culture. Additional study aids include tone-coloring options and resources for exploring Mandarin and Cantonese pronunciation. The site is designed as a practical companion for building Chinese reading, vocabulary, and writing skills.
