If you prefer not to take a city bus, taxi can be a good option to save trouble. Taxi in the city charges CNY7 for the first 2km (1.2mi) and CNY1.5 for each additional kilometer (0.6mi) within 8km (5mi). If a ride is farther than 8km (5mi), it costs CNY2.25 per kilometer. Some taxi drivers may not charge by meter. Under the circumstance, it is suggested to negotiate for a flat rate. For poor service or possible fraud, you can make a complaint by calling 0538-12328.
