Before the Nationalist government retreated from the mainland in 1949, the remittances of Kinmen emigrants living in Taiwan and Southeast Asia were an important source of economic support for each clan. Many of the mansions in Kinmen Town and many of the schools in the villages were built with remittances.
在民國三十八年國民政府撤退之前，移居台灣、東南亞僑民的「僑匯」就曾是金門各姓宗族的重要經濟支柱，現在金城鎮的許多巴洛克式洋樓及許多村落的學校，都是僑匯建造。
