what bus going from zhangjiang to yuyuan garden, shanghai?

May I know if you will start from Zhangjiang Hi-tech Park? If so, Xuchuan Special Line can take you to commute between, but it would take around 20min to the garden after getting off at Lujiabang Road Kualong Road. Actually, metro is a better choice. Take line 2 to East Nanjing Road and transfer to line 1. Get off at Yuyuan, leave from exit 1 or 3 and walk to the garden in 3-5min.
