Introduction to the Xiaguan Hall: The light in the Xiaguan Hall gradually dims, making it eerie and eerie. If you shine it with a torch, the golden light from the cave wall will reflect back, like gold and silver, which is dazzling. The birds and animals formed by stalactites are various and vivid, such as lion ball, turtle stone, longevity star fairy rock, Yuquan silver waterfall, etc., which makes people feel like "the angry stone looks like a sea fairy, and the mirage is wonderfully stacked beside the colorful clouds" . According to legend, the Ming Dynasty sent General Qi Jiguang to garrison the Quzhou silver mines. Wei Zhongxian used to discuss affairs and pass decrees in the cave, relax and escape the summer heat, so it was named "official hall".
