In 1944 AD, the Japanese military enslaved residents from Wang'an and Jiangjun Islands to excavate it, serving as a base for naval torpedo boats and a dormitory for special attack unit members. Just as the construction was nearing completion, Japan announced its unconditional surrender, and the base was subsequently abandoned. Many of the caves have long since collapsed, but some relics are still faintly visible.
