The whole lake is shining in the sunlight, just like a large piece of excellent transparent jadeite. When you rowed a kayak into a waterway enclosed by limestone cliffs, the green water spread like a fan with drills. Limestone mountain blocked the waters into two lakes. If you want to cross, you must get off the boat. The scenery along the way was dazzling. The alternating cold and hot currents pushed the mood to the highest point.
