It is also called “Longtan Pool”, located in the vally between Yunfeng Peak and Chaxiao Peak. It is the place where Qianchi Spring and Jiuhua Brook meet, and is named after Longxi Brook. Folk legend holds that Longchi is “unmeasureably deep and forever full, a place where a dragon lived”. Longxi Brook rushes fast between two cliffs, like an arrow on the bow, down quickly to the rocks in Longchi, so the waves crush and sound like peal of bell.
