Hi I need to get to Huai'an after an international flight in Shanghai Pudong.

According to your timing, I’m afraid no public will be available to your destination on the same day. It is suggested to stay in Shanghai for overnight and head there in the next morning. At the General Long-distance Bus Station near Shanghai Railway Station, there are many buses for your choices from 05:40 to 18:35. It takes 5-6h and costs CNY138.
