Kinship and clans have played a very important role on Kinmen. Today, many villages remain inhabited only by families of the same surname, such as Cai Village, Yang Village, Ou Village, and Chen Village. Temple fairs, which are the highlights of Kinmen's folk activities, are held from time to time in the villages. In a village temple fair activity, villagers worship their common ancestors and god-protectors; they also parade with the statues of village deities along the village border to scare off wandering and evil spirits. The biggest of Kinmen's annual folk festivals is the one held to celebrate the birthday of the island's Town God, protector of the island, on the twelfth day of the fourth month of the lunar calendar. On the day, the Town God, accompanied by deities invited from the countryside and devout worshippers holding burning incense, patrol the streets to frighten away evil spirits and ghosts in the deafening sounds of gongs and drums. Every household of the town prepares rich offerings, and invites their good friends and relatives from the countryside to join the celebration. In addition, folk performances such horse-formation performance, gong-and-drum -formation performance, puppet show presentation, and local opera presentation all add spice to the activity.(Temple Fairs)

Cheng-Huang Miao (City God Temple) was built in every administrative center since Min Dynasty. There are three temples of the City God in Kinmen.  Cheng-Huan in Tien-pu, Chinsha, is the oldest. Kinmen-Cheng was the administrative center in Min Daasty.  Cheng-Huang Miao was built there.  In 1682, it was transferred to Ho-po, Kinchen.  The day of the move was on the 12th of April in the Chinese lunar calendar.  It has been the anniversary of Cheng-Huang ever since.

April 12th of the lunar calendar is considered one of the important days by Kinmeness.  The majority of people come back to Kinmen to celebrate the special day.  Cheng-Huang Miao is crowded with worshipers.  Celebrations include worship, parades, operas and folk performances.  Residents in Ho-po feast their friends and relatives on that day.(金城國中課程教案設計表 / 編寫者：張浩然,羅毓華)

Although Kinmen is quite a small island, it has over three hundred shrines and temples. Since the sea surrounds it on all sides, and in the past the people relied almost entirely on it for survival, the islanders have traditionally regarded making offerings to the gods as of utmost importance.

The tour of the Wudao city god to other temples and shrines has become a grand event on Kinmen. The city god is simply the god that is set up within a city to protect it. The original idea of protecting the city has also, with time, been extended to include the city, its walls and the surrounding moat. Gods of other local shrines and temples in this festival also visit the city god. Over the years he has also been incorporated in ceremonies wishing for rain, requesting fair weather, and asking for good fortune and protection from disasters.(Festivals of Kinmen)
