Borneo is the third largest island in the world, under the jurisdiction of Indonesia, Malaysia and Brunei. It is currently the only island in the world that belongs to more than two countries. The northern part of Borneo is the whole of East Malaysia, and the administrative district is Sabah and Sarawak. The northernmost corner of Borneo Island is located in the ancient town of Sabah in Sabah. The locals call it Tanjin Xinbang Meng Ayao. The Chinese call it Lighting House or End of the World. There is also the vast seawater junction between the South China Sea and the Sulu Sea in eastern Sabah. The local government has built an iconic building here, a sculpture that shows the latitude and longitude and the entire Borneo map. Ascending the three giant rocks facing the sea, overlooking the vast South China Sea, I saw the water and the sky, and I felt that the sea was wide and the sky was clear, and it was unbearable to give birth to a heroic feeling.
