Because most of the villages of Kinmen are made up primarily of a single clan with a common surname, the entire community often counts as one big family with a shared blood line. Therefore, the local people are particularly concerned about clan relations. There are more than 160 ancestral temples, covering every single surname, the most of any county in the Taiwan-Fujian area.
由於各村落以「一姓村」為主，聚落就是一個大型的血緣家庭，所以當地特重宗族關係，單單各姓宗祠就有一百六十多座，為台閩地區宗祠最多的縣治。
