How to go yuyuan garden from my hotel at charm hotel that location at jiu jiang road, huangpu dist?

Well, it’s not a long distance, so you can take a taxi there. It costs around CNY14 and takes about 5 minutes. Or take Bus 805 to Xinbeimen, and then walk south for 5 minutes, you will see it. It takes about 10 minutes and CNY2.

How about use metro? What line can i use?

Dear, metro is not a good choice. Since you need to walk most of the trip, just as follow: walk east for 10 minutes to Nanjing Rd (E) to take line 10, and get off at Yuyuan. After that, go out from Exit 1, and walk east for another 10 minutes to the garden. It costs CNY3.
