Dictionaries are repositories of lexical data. They preserve all kinds of linguistic and cultural information about a language. They can help minority people learn the national language and improve their skills in their own language. So far our work has resulted in a Zhuang dictionary and work on Yao and Bai dictionaries is in progress. In 2000 EAG ran a lexicography workshop in Nanning, and in 2001 another in Beijing.
