"how to go to shanghai jade buddha temple from east nanjing"

You must refer to East Nanjing Road, right? Well, there are two ways for you:
1. By bus: walk from where you are to East Beijing Road/Middle Henan Road bus stop to take bus no. 19 and get off at Jiangning Road/Anyuan Road. Then walk to the attraction within 200m.

2. By MTR: take subway line 2 at East Nanjing Road MTR Station to transfer to line 7 at Jing'an Temple and get off at Changshou Road Station. Get out from exit 5, and walk along Xinhui Road to turn right at Jiangning Road. Then you will see the temple.
