Introduction to the Nine-hole Bridge: The jagged rocks in the stream in the Yuwan Scenic Area, the surging water, and isolation by stone dams form waterfalls and pools. One of them is called: 'Three Pools Jilang', which is located in the upper reaches of the stream. There is a nine-hole stone bridge. There are many dragon heads carved on the bridge railings, but each of them sprays water outwards, forming a three-dimensional fountain.
