Gaojia is a city in Jiangxi province, China. It is located in the eastern part of the province, within the broader Jiangxi region of southeastern China.
The city shares its name with Gaojia opera, a form of Chinese opera that originated in Quanzhou in southern Fujian province, not in Jiangxi. That operatic tradition emerged at the end of the Ming dynasty, developed from an improvised performance style performed during religious parades, and is known for its various clown (chou) roles. It later absorbed influences from Hui opera, Beijing opera, and Yiyang music, and is also known in the Philippines as "Kaoka," where it is considered a dying tradition.
Beyond its location in Jiangxi, the available reference material does not describe the city of Gaojia itself, so no further details about its characteristics can be confirmed here.
