Kunming, the night, revealed the mysterious light and dark, a hundred years of stone road like brushed a layer of oil, the light of the street lamp in a crystal clear way. I have been to Kunming nearly ten times, and I am still surprised. The old street floor is what I have ignored, or renovated in two years, and I can't tell myself. But I am more and more convinced that a word, happiness and unknown is like water in a sponge, squeezed always will have, huh, huh.
