In certain unknown age, residents in Zhongshan Village, Dongshan Township gave names to two waterfalls from different directions. One is ''Jiuliao Waterfall'' and the other is ''Sinliao Waterfall.'' The latter is younger, the current is swifter, and the volume of water is more plentiful. Liao means wooden or grass cottage. Smart ancestors built a temporary shelter with local materials so that they could climb up the mountain, collect camphor trees and draw out the rattan. Dongshan River is called ''the river of hope,'' and its source is Sinliao Waterfall. There are green whirlpools and clean bubbles in the deep pond below the flushing waterfall. The spraying water drops make the pond cool even in summer. Soaking feet in the cool river, the cold water makes people feel comfortable. The spring strikes the pebbles and gives forth sounds. Visitors stand below the cliff and listen to the chirping of cicadas and birds. There are tadpoles, frogs, dragonflies, mayflies, and butterflies on the water. Due to the inconvenient transportation, there are not so many people enjoying the pleasure at the waterfall. It is another wild pleasure.
