In 1877, after a flood in Yunyang, Hubei, many displaced people moved into the Shangluo region and brought a popular Huagu opera with them, according to China’s national intangible-heritage project record. Over time, performers sang in Shangluo speech and drew on local folk melodies. The travelling form became known as Shangluo Huagu, also called Huaguzi or Dibengzi.
The project account describes two regional traditions. Shangdan (商丹路), associated with the northern part of the area, mixes Guanzhong speech with local words and has flowing, gentle tunes. Zhenzha (镇柞路), associated with the south, blends northwestern Hubei speech with local expressions and is described as brighter and more forceful. Together they show how a theatre changes when its words and musical cadence meet a new community.
