We know that smoke from cigarette is really not good for our health. These days our air contaminated with many pollutant. Cigarrate is responsible for this. These contaminated air will causes many risk for our health. Know that Seoul Metropolitan Government will expand No-Smoking Zone is really great. This policy will make the clearer air and comfort a lot of people. I always dream that I can stay away from smoke. Reading this new policy increasing my interest of Seoul. Its really great if we can live in modern city with beautiful scenery and clear air.
