is there a taxi to go from nanjing to qingdao ? tomorrow i have to be there tomorrow.

Oh, I'm afraid that there is no taxi from nanjing to qingdao.
You can take high-speed train from the south railway station of the city. It will take less than 5.5 hours on the way.

Or you can take a train or long-distance bus.
And it takes around 10 hours on the way.

You can choose what you like. :)
