The name WuKuei (“black ghost” ) gave a sense of mystery. According to the inscriptions documented on the coral reef wall, WuKuei Cave once witnessed the blood history of the black slaves.During Yongli Year in Ming Dynasty, Cheng Chen-Kung (Koxinga) drove the Dutch away and successfully reclaimed Taiwan and Penghu. However, some black slaves shipped to Taiwan by the Dutch to serve as slaves were left to die on Little Liuqiu. One by one, these black slaves hid themselves inside the caves of Little Liuqiu. It was not until a couple years later that a ship carrying British soldiers landed on Little Liuqiu’s Haban where they were robbed and nearly wiped out by the black slaves. Shortly after, British reinforcement troop discovered the tragic accident and started their merciless revenge by setting all black slaves living the cave on fire. In commemoration of the event, the cave was thus named, “WuKuei Cave”.During the time of living in the cave, black slaves left many stone bowls, stone chairs, stone tables, stone beds and various artifacts with rare discovery of jewelries and silverware. Regrettably, the entrance to the cave is now completely blocked and inaccessible due to cave collapse. Although WuKuei Cave is a site of tragedy, visitors will linger and praise its natural sceneries with their fears forgotten.WuKuei (coral)Cave Scenic Spot is located at the southwestern tip of Little Liuqiu with sight-seeing spots including Hao-Jan Pavilion, Bi-Tao Pavilion, Gan Spring (Sweet Spring), Yi Bridge, Lie Pond, Yo-Ching Valley, Bie-Yo-Tian, and the most famous coral reef cave. Hidden inside the slopes, the coral reef cave is like the maze of the Scenic Spot with its narrow and winding cave spaces. The Cave is dark with minimum visibility. Visitors who wish to enter the cave must bring a flashlight to ensure safety.Embedded in the coral reef cliff near WuKuei Cave are two giant clam fossils. According to research, these two giant clam fossils are tens of thousand years ol
