which is the Nearest International airport for Zhejiang Province

For Zhejiang Province, I think the closest international airport is the Hangzhou Xiaoshan International Airport.
BTW, which city do you leave to enter China? If you can tell me, I may help you to check whether your city has flight to HZ Xiaoshan airport.

I have to go here.

Jinchuan Road,Development Zone,Huangyan,Taizhou
City ,Zhejiang Province

From Mumbai

to

Taizhou
City ,Zhejiang Province

From your country, there is no flight to Xiaoshan International airport, so you may need to fly to SH first.
The use the SH Subway line 2 to reach Hongqiao Railway Station where you can find bullet trains for Taizhou. Upon reaching Taizhou city, you can take a taxi to Jinchuan Road, Huangyan District.
