Hello every one I feel happy that I amliving in a village in Trung thanh conmure of Thai Nguyen province. It is a peace ful place with fresh air . We can enjoy a healthy natural condition without worrying much about air pollution . Moreover , rural is a safer place than a city . Because most of the villagers are friendly and wiling to help each other . There is less traffic so it's safe for children . The special thing that people like living in the countryside is the cost of living here usually cheaper so this is on idea place to rai se the child. In contrast , the bad things are very rare in the country side. To sum up, except the problem of income, the countryside is a residence better than the cities
