區域文化的形成是一個漫長且複雜的歷史過程，語言、習俗、宗教等都是這個過程中極為重要且富有活力的要素之一。潮州雙忠信仰始於南宋咸淳年間，因為雙忠信仰具有守護城池與教化民眾的功能，明代以來，地方官紳積極倡導廟宇的修建與祭祀，至清末，潮州屬縣縣城均有雙忠廟建成。這主要是由官紳倡導的信仰傳播，可視為同一文化區域內官紳文化認同的自覺映射。在這個過程中，廟宇的建立與潮州區域文化相互促進。

The formation of regional culture is an endless and complicated process, where many dynamic elements including language, custom, religion, etc. are continuously interacting with each other. Belief of Twin Loyalty in Chaozhou began at the reign of Xianchun in the Southern Song Dynasty. Since Ming Dynasty, local officials and the gentry were willing to lead the construction and the sacrifice of temples of Twin loyalty because of its characteristic function of protecting city and edifying the local populace. At the end of Qing Dynasty, at least one Twin Loyalty temple was erected in almost each county town of Chaozhou. These spread primarily presided over by the gentry and officials can be regarded a reflection of their identification with a unified regional culture, which evinces that establishments of temples and Chaozhou culture are intertwined.
