Mandarin Duck Cave,藏軍洞 Introduction
Yuan Yang Play Water - Yuan Yang Cave is located in the northeast of Wang'an Island. It is a natural valley terrain, and legend has it that the area was named because there were many water caves where mandarin ducks frolicked and roosted. The outer sea is protected by Saddle Mountain Isle, which resembles a saddle; thus, during the Japanese occupation, it was developed by the Japanese military into an important naval base, with the "藏軍洞" (Cangjun Cave) being a remaining historical site in the area. In 1944, the Japanese military enslaved the residents of Wang'an and Jiangjun Islands to excavate this site, turning it into a naval torpedo boat base and dormitory for special forces. Just as the construction was nearing completion, Japan announced its unconditional surrender, leading to the abandonment of the base. Many caves have since collapsed, but some remnants can still be seen.
