3.1 Yanliudong/Yanliusuidao
Yanliudong is a massive cliff-walled collapse doline 100m x 200m at the bottom of which the main river is encountered. This entrance was descended by a 150m free-hanging abseil. Yanliudong is part of the hydroelectric scheme and an artificially enlarged passage leads off for over 11⁄2km to Yanliusuidao, where an irrigation pipe follows a branch passage leading out into a muddy-bottom doline that is actively farmed in the dry season.
