For the most part, Digital Chinese Humanities is rather new and emerging. DCH examples include the following:
China Biographical Database (CBDB by Harvard and PKU) is a freely accessible relational database with biographical information about approximately 360,000 individuals as of 2016, primarily from the 7th through 19th centuries. With both online and offline versions, the data is meant to be useful for statistical, social network, and spatial analysis as well as serving as a kind of biographical reference.
Chinese Civilization Time and Space, by Academica Sinica in Taiwan "in response of the demands of interdisciplinary research applications, this system aims to construct an integrated GIS-based application infrastructure within the spatial extent of China, in the timeframe of Chinese history, and with the contents of Chinese civilization." (Changes of Names, Borders, Places, etc.)
Classical Historiography for Chinese History from Princeton, the site pulls together materials of interest to anyone doing research in Chinese history (broadly defined) but with a focus on the Ming (1368–1644) and Qing dynasty (1644–1911).
Digitizing Chinese Englishmen, a digital project that focuses on the creation of “Asian Victorians” in Southeast Asia under British colonialism. It concentrates on the digitization and annotation of the Straits Chinese Magazine, a journal produced by the Chinese diaspora in Southeast Asia in the late 19th and early 20th centuries.
