how to get back from Shanghai Animal Park?

I'll stay at Sofitel Hyland & use line 2 subway station, stop at Zhangjiang Hi-Tech Park Station, exit 5 then take Zhangnan Bus line.

But I still confuse how to go back to the Zhangjiang Hi-Tech Park Station.
1. Could I use the Zhangnan Bus line to go back into Zhangjiang Hi-Tech Park Station?
2. if yes, should I wait in the same bus stop when arrive to the park?
