Chinese Guoxue is a free online Chinese dictionary and character-learning resource designed to help users look up and understand Chinese characters. The site brings together dictionary entries and reference tools, covering characters found in the Xinhua Dictionary as well as a much broader collection. Users can search by character, pinyin, radicals, stroke count, and several input or character-encoding systems, including Wubi, Cangjie, Zheng code, Unicode, and four-corner codes.

Entries provide pronunciation, meanings, explanations, examples, usage information, and related references. The site also offers writing animations and stroke-order guidance for more than 9,000 characters, along with tools for examining character components and searching by handwriting or other methods. Additional resources include idioms, vocabulary, synonyms and antonyms, the Kangxi Dictionary, Shuowen Jiezi, and collections of unusual or commonly used characters.

By combining lookup functions with historical and writing references, Chinese Guoxue serves students, language learners, and anyone seeking practical information about Chinese characters
