If you think enforcement of the new smoking laws are bad in Kunming, you should see it in a second level city or county seat! Down here no one knows that that any new national laws regarding smoking in public came into effect this year. No matter where one goes, restaurants, buses, bus stations, airport, police stations, grocery stores in the smaller cities of Yunnan, one breathes second hand smoke. And the idea that second hand smoke adversely affects the health of others, is apparently so ridiculous it's humorous to otherwise well-educated people. In years of residence in Yunnan, I've still never seen a billboard against smoking outside Kunming, but I've seen a number of rural areas with large signs about "turning X area into the new modern tobacco cultivation area..."
