Introduction to Longtan Lake: The lake surface is winding and exquisite, the water is clear and deep, the slopes on both sides are gentle and densely forested, and the mountains are full of flowers. The four seasons are endless. In spring, there are peaches and plums welcoming the drizzle, in summer, the mountains are red with azaleas, and in autumn, wild chrysanthemums are flying. Snow, wintersweet, proud of frost and cold.
