The Pearl Sea is called "Zhuomalacuo" in Tibetan, and is a sea of snow formed by the snow of Xiannai. The area is about0.1 square kilometers, and the pearl sea in the dense forest is like an emerald set on the lotus throne. The sparkle is infinitely clear, and the lakeside is surrounded by greenery. A half-hour steep walk from Chonggu Temple to the Pearl Sea is the ideal place to take a reflection of the immortals.
