The Zhuang are primarily lowland dwellers, who are traditionally an agricultural people. They grow rice in both plains and steep terraces and they raise livestock. They have a well-developed art and handicraft style. They are very musical, capable of composing impromptu verses in songs, to be sung in festivals or in courtships. They have a very rich oral literature. One of the most important pieces is the Baeu-ro-do epic song, which has been the subject of a detailed anthropological study (Holm 2004).
