These karst peaks are located in Huaiqun town in Hechi's Luocheng Mulam autonomous county. A huge natural arch, with a height of over 100 meters and a width of 30 meters, frames a magnificent and marvelous landscape. The top of the hole is curved; various stalactites hang down from the arch, and the Jian River flows through the gap. The landscape is so graceful it can make tourists feel light-headed.
