If we are at the Nanjing Hotel which is situated at 200 Shangxi South Road, can we take the Subway line 1 to get to the Shanghai Circus World or do we have to take the Subway Line 2 first then transfer at People's Square to Subway Line 1? Please clarify as we are confused. Which is the easier &/or the nearer route & more convenient one for us? Thanx a lot.
