Zairan' city- how it has changed (Shi jiazhuang, China)

My hometown is not a big city, but with economic development it has made many changes in recent years. Because of influx of the population and the increase of private cars, many streets have been increasingly able to meet the needs of people no longer. Some narrow streets have been expanded its area and old roads have been renovated. Furthermore, my city' tourist industry develops rapidly, that' why a great deal hotels have been built to replace the ole ones, which are demolished in large area. With the seriousness of air pollution, many industrial factories have moved to the suburbs to make way for shopping malls, schools and hospitals. A decade ago, the infrastructure was too bad, but rencently our city has constructed a lot of new infrastructure.
