Xuhai Police Station is located in the east of Xuhai, at the intersection of the end of Pingtug 199A Highway and Taiwan Provincial Highway 26. Because it is located on Hengchun Beinan Road, the junction of Hengchun and Taitung, its location is extremely important. In the early days of the Japanese occupation, the Mudan Bay Police Station was established here. It was moved next to Xuhai Elementary School at the end of the Japanese occupation and was re-established after the war at the current location. To the northeast of the police station is the Donghai Tribe. The Donghai Tribe was originally a working dormitory built for fishing convenience. Later, some people settled down and formed a small settlement. The Amis with the surname Pan and the descendants of Pan Abie are the main ones. In 1976, a new pier was built in the north of the tribe, where boats and rafts can dock. Half of the residents are fishers and half are farmers.
