The lighthouse Fang Laosi is not open to the public and can only visit outside. The lighthouse Fanglaosi was built by the Fang family in Qiangya village in the ninth year of the Republic of China (AD 1920). It was originally called "Guxifu" and was named after the name of the Fang family's ancient house and the stream that once flowed by the building. The building is 5 stories high, 18.43 meters. Below the third floor is the dormitory of the staff on duty. There is a balcony on the fourth floor and a western-style dome pavilion on the fifth floor. The building is equipped with early western generators, searchlights, guns and so on. Used for early warning on duty, which is a typical upgrade. Historically, Fang's lantern house has played an active role in early warning and defense for the local people in Guzhai Township to prevent bandits from attacking Magang area in the north, so the present situation is not open to the outside world, so they can only visit the periphery.
