Exercise in Nature

When I was in China, it was amazing to me that people are getting from sleep going outside of the house very early in the morning. All the streets, roads and open areas are filling slowly with peoples. They do exercise with music. They love nature. Nature isn't made by humans and now and again we become shocked with heavenly bodies, waterway, sea, wandering animal, land structures, trees, cascades, cavern, mountain, and even a little bug, massive misuse.  

 Natural air is pure and especially very early in the morning. I was also very astonished that some old people are doing Kung Fu practice even at age 85.
