Beiguan is a type of silk-and-bamboo music widely popular in Quangang district, Quanzhou in Fujian province, and is also performed by beiguan ensembles in Taiwan, Singapore, Malaysia, and other regions.

During the early years of Emperor Guangxu (1871-1908) in the Qing Dynasty (1644-1911), folk music from the Jianghuai region was introduced to Quangang district, Quanzhou, via maritime transport vessels, gradually evolving into the Quanzhou beiguan music that has been passed down to this day.

Beiguan can be divided into two main categories: qu (vocal music) and pu (instrumental music). The qu pieces primarily originated from the Jianghuai folk tunes of the Ming and Qing dynasties (1368-1911), while the pu pieces were largely derived from Cantonese music, Jiangnan silk-and-bamboo music, and Beijing Opera melodies.

The lyrics mainly feature narrative and emotional expressions or depict scenery through song, performed in guanhua (the historical Huguang dialect, similar to modern Mandarin).

During the prelude and at the conclusion of musical phrases or sections, singers often accompany themselves with percussion instruments while vocalizing. The singing style also incorporates techniques from Puxian music and Nanyin.

Conducting thorough research and documentation of Quanzhou beiguan plays a significant role in studying the historical connections between Taiwan beiguan, Japanese Uzagaku, and Quanzhou beiguan.

It also holds great importance for understanding cultural exchanges and commercial trade between China and Japan, Fujian and Taiwan, as well as the interactions between Quangang (Fujian), Guangdong, Jiangsu, and Zhejiang provinces.
