Both surnames are local surnames, and this place is called "Qilu, half the population of Bird". Jingtang Temple is the largest and most famous temple in Qilu Mountain. According to the Genealogy of Zhang V in Fanling, Zhang moved to Qilu Mountain Town from Yongfeng in Ji 'an in the Tang Dynasty, and his ancestors were prolific. This temple was built by the local Zhang family to worship the Zhang ancestors, mainly to worship the local Zhang ancestors and Lai Gong brothers.
However, in addition to paying homage to Zhang's ancestor, there is also an ancestor Fu Xianggong who moved from Gongjiang in the late Ming Dynasty and early Ming Dynasty, so the relationship between Zhang and Yuan can be regarded as the relationship between indigenous people and refugees in Qilu Mountain Town. In this way, there are more local surnames.
