The Dagu Iceberg in winter is so beautiful! Alpine lakes are stratified in color. The more they go up the mountain, the more they are covered with snow. The Lake begins to freeze and finally the frozen people can walk on it. The top of the mountain is more like a pure land. The blue sky, white clouds, trees, lakes, mountains, monkeys, yaks and eagles all left a deep impression on me. It's a worthwhile trip.
