The sun rises out of the valley, the vast Milky Way slowly exits, and the adventure of the mountain fairy tale begins officially. The ups and downs on the seesaw, the laughter of children on the sand pool, the wanton joy of children, cheering between the swing and the falling slide, in order to release the nature and imagination of children, we will have the innocent smiling face in the eyes. Perhaps those dreams about the wonderful world, in the experience of joy quietly sprout.
