I come from Shanghai Airport to zhejiang. are there train or bus to zhejiang from shanghai airport?

No train from the airport directly. But you can take long distance bus from the airport. Buses from the two airports can reach to Hangzhou, Suzhou, Wuxi and other cities.
Or you can take airport shuttle to Shanghai South Railway Station to take high speed train to reach your destination. From Hongqiao Airport you can take subway line 10 to Hongqiao Road, and then transfer to line 3 to reach. From Pudong Airport you can take airport shuttle line 7 to reach.

thanks dear. how much time by bus from airport or train station? better by bus or train? and cost of them please?

As you post your question on this page, I presume you wanna head for Hangzhou City, the capital city of Zhejiang Province. Well, if from Pudong Airport, you are suggested to take the direct bus to reach. It takes around 3h. If from Hongqiao Airport, you can walk to Hongqiao Train Station to take a bullet train to arrive in 1.5h.
