Let's join the World No Tobacco Day

May 31 each year is the World No Tobacco Day, the saying "Smoking is hazardous to health", is known to everybody, but due to habits, temptations and other reasons, smokers often ignored their health and environmental pollution. Please encourage smokers to determine to quit smoking and to prevent others from the harm of secondhand smoke. Let's establish a practical plan in the World No Tobacco Day, and construct a smoke-free home and a fresh community.
