Some people say that it is only when they come to Kinmen that they begin to understand "Southern Fujian." Both architecture and culture reveal a strong sense of ancient taste. On the island of Kinmen, there is also a great place to experience the island style - Jiangongyu. However, even the Kinmen natives have not visited Jiangong Island because it was once a quarantine area and a military management area. It was only opened as a tourist attraction in 2003. Jiangongyu is only about 500 meters away from Kinmen Island and covers an area of about 500 square meters. Because the sea is surrounded by the sea when the tide is high, you can only wait for the sea to retreat if you want to walk to the island. A tide rising road is hidden, and the current seabed stone road that makes the tide retreat makes Jiangong Island full of the unique and independent temperament. Can you go to this island to fully appreciate the mood of luck and the sea. During the late Qing Dynasty and the early Republic of China, people knew little about leprosy, so they sent the leprosy patient here to isolate it and let it go its own way. It was named after the leprosy. Later, due to its geographical location, the Jiangongyu became a military center, and a small island was full of historical mystery. Coincidentally, it is precisely because of the inaccessibility, Jiangongyu preserves a good natural landscape, and the intertidal ecological belt is complete and interesting.
