The local Electronic City near the local Cultural Park is suggested for you.
For the GZ Shipyard, do you refer to the local Shipyard International Co., Ltd
If so you can walk or take a taxi to reach Xilang Station of local subway line 1 to take line 1 to reach Chenjiaci Station. Then you can take a taxi to reach the Electronic City at No. 37, Xidier Road.
Or you can direct take a taxi from your company to reach the market and the market is about 7km from your company. The taxi fare is around 25RMB.
