Fly to Pudong first and ten take airport Bus Line 5 to Shanghai Raiwalway Station. Them take bullet train to Zhenzhen within 1 houtr and 50 minutes to Zenzhnjiang.

I'm an Asutralian who has been teaching in Zhenjiang since 2004. The easiest way to get to Zhenjiang is to fly into Shanghai, and get the bullet train to Zhenjiang. Alternatively you can fly into Nanjing, the capital of Jiangsu Province and get the ordinary train or bullet train to Zhenjiang. Zhenjiang is 1 1/2 hours from Zhenjiang by car or bus. Zhenjiang people are very friendly.

Sorry, I made a mistake in my previous advice. I said Zhenjiang is 1 1/2 hours from Zhenjiang by car. It should read: Zhenjiang is 1 1/2 hours from Nanjing by car!
