Wang-an - Mandarin Duck Cave, Zangjun Cave (Zhenyang Boat Base) Introduction
Yuan Yang Cave has geographical and historical value, featuring an east-west river valley topography and serving as a sea fishing spot. The nearby river valley terrain is home to several shallow wells. During World War II, it also served as an air raid shelter for the residents of Wang-an, where multiple caves were excavated for this purpose. Over time and due to natural forces, most of these air raid shelters have collapsed. The surrounding beach of Yuan Yang Cave is pure and tranquil, while the outer sea is shielded by Saddle Mountain Island, which resembles a saddle and is about 600 meters away. The "Cang Jun Cave" within Yuan Yang Cave is a remnant historical site; during World War II, the Japanese military enslaved the residents of Wang-an and Jinmen Islands, digging out this cave as a dormitory for torpedo boats and special forces. The construction was completed just as Japan announced its unconditional surrender, leading to the abandonment of the base, with many of the caves already collapsed, leaving only ruins. [Recommended stay duration] 2 hours.
