Introduction to Wolong Sea: The blue color of the lake is so thick that it cannot be melted away, which is intoxicating. The water surface is as smooth as a mirror, with speckled waves. A long milky white calcified embankment lies in the middle of the lake, like a dragon swimming under the water. The breeze passed by, causing ripples. The dragon's body squirmed slowly, and its scales were faint and flickering. Wherever the strong wind passed, the waves were blurred, and the dragon's shadow suddenly disappeared. It was mysterious and breathtaking.
