i need go to zhejiang from nearest air port and stay 3 night in the hotel close to air port and

Could you tell me which city you are in? Do you want to travel to Gongguan or Zhejiang, or both? I cannot grasp the meaning of your question.

Hi Michelle.

I am from srilanka and I want to visit factory at Jiashan in zhejiang what is the close airport to Jiashan and city as i am planing to stay 3 days i wish to shopping and travel to Dongguan city

Well, you can go fly from Colombo to Shanghai Pudong International Airport. Then you can go to Shanghai Hongqiao Railway Station where there is bullet trains for Jiashan directly. Shanghai Pudong International Airport is the most convenient airport and is not far from Jiashan. The train will take you about 20 minutes to arrive at Jiashan.
Since Jiashan is close to Shanghai instead of Hangzhou, I advise to go to Shanghai Hongqiao Airport to fly to Dongguan. You can take the bullet train from Jiashan to Hongqiao Railway Station, which is close to the Hongqiao Airport. Then you can fly to Dongguan directly.
