###### The quiet Nansong River, the magical karst terrain, the strange caves, and the traditional Lao villages nearby, I especially like it. Through a school, the children laughed at the playground, so we couldn't help but stop. laugh, is the most beautiful language in the world. Other than that, we can't communicate in other languages. The children are free to release their nature by the river, just like the days of returning to the Garden of Eden. Such a simple life.
