Because of the erosion of the passing Liwu River, after a long time, the valley changed to the U shape with steep cliffs at both sides. Several devious tunnels were excavated here during the pavement of Central Cross-Island Highway. Visitors could walk through the tunnels, enjoy the stream below the cliffs, and watch the swallows fly at the other end. Standing on this marvellous landscape, you cant help but admire the profound greatness of nature and manpower.
It is a pity that the excessive number of visitors scared the swallows away, and only the cave views are left for awe.
