Asia's longest cave has many wonders

"The length of a cave system equals the total length of all its main caves, branch tunnels, cenotes and underground rivers," said Qian Zhi, secretary-general of Guizhou Cave Association.

A team of Chinese and French speleologists announced at a Saturday news conference that the surveyed passageways in Shuanghe Cave had reached 238.48 kilometers, making it the longest in Asia. Previously, the longest known Asian cave was the Clearwater Cave in Malaysia, with a length of 222 km.
