Would like to know how to get from Wuhan airport to Tongcheng city by Taxi and how much?

It is about 200 kilometers between Wuhan and Tongcheng City, so the taxi fee is a little bit expensive.
Bus is the suggested way. You can take the shuttle bus from the airport to the Hongji Bus Station, which will cost you about an hour and a half minutes to go and 32 RMB. Then you can take the coach from the station to Tongcheng City directly from this station. The ticket price is 63 RMB and cost you about 3 hours.
