Thirty years of 'opening-up' has changed China in a big way that has astonished the world. That 30 years saw China transformed from being a poor and weak nation to one that is strong and progressing steadfastly into a modern developing society. She has uplifted hundreds of millions of citizens from poverty to reasonably good and comfortable living. All these achievements don't come easy without tears, blood and sweat.
I’ve lived in China for quite a considerable time including my graduate school years, travelled and worked in a few cities and still choose my destination taking into consideration the density of smog or PM2.5 particulate matter in the region.
