Pearl Sea is to see the reflection of the immortal day. The sun is not enough. Otherwise, when we go too late, the sun is too strong, we can only see the green lake water. With the strong wind, it is not easy to take the whole reflection. The scenery there is very beautiful, and it is not as hard as climbing the milk sea. We climb up and down the ancient temple road. Generally, if we have good physical strength, it takes less than two hours to go back and forth.
