Its independently deployed services help researchers and readers work with historical maps, calendars, Chinese characters, texts, and fonts. The platform is designed for practical use: its tools require no registration, display no advertising, are continually maintained, and are built to work across phones, tablets, and desktop computers.

Featured resources include the Shouxing Calendar, which converts between Gregorian and traditional Chinese dates across a span from 4713 BCE to 9999 CE, and a China Historical Atlas with searchable place names, period-based map layers, and overlay comparison. Users can search Chinese characters by components, consult an online edition of the Modern Chinese Dictionary, and compare or download open Chinese webfonts. The Jigmo webfont service supports rare and variant characters, while the CBDB query service enables searches across historical biographies and relationships. The collection also links to classical-text search, Chinese conversion and glyph-variant tools, and a standard-character reference. An open-source pinyin dictionary is available for developers.
