Reservoir introduction: The beauty of the ancient road lies in the clear water. In the twists and turns of the ancient road, which seems to have no path, there is a place that suddenly opens up. This clear water pool is like a miniature version of Taiwan's Sun Moon Lake. It is like a flawless jade, hidden deep in the mountains, undisturbed by the world, pure and mysterious. Whenever the sun sets, the water in the pond is sparkling, and occasionally a few egrets fly across the water. Standing by the water, the scenery of lakes and mountains comes into view.
