North Border of the Country Introduction
Standing at the northernmost point of Taiwan, many people are aware that the southernmost boundary of the Republic of China extends to the Spratly Islands' Zengmu Ansha, but few may know that the northernmost boundary is located at Dongyin in Matsu. By proceeding northwest along the road from the Qing Shui Ao control post and climbing over the hill, you will reach the northern frontier of the Republic of China. However, the true northernmost point of Taiwan is actually a small reef located off the coast of Luohanping Cape! This reef, also known as Beigu Reef, is situated about 600 meters above Hou Ao in Xiyin. Currently, the reef is uninhabited and can sometimes be submerged or revealed depending on the tide. To commemorate this northern boundary and provide tourists with a view, the Matsu National Park Administration has built a viewing platform at Hou Ao Cape and erected a stone plaque inscribed with "National North Boundary," allowing visitors to take photos as a memento, even if they don't see Beigu Reef, proving they have visited the "top of the nation."
