Shanghai Sceince & Tech museume to nanjing road ??how long it takes?after how many metro stations?

From Shanghai S&T museum (underground Fake market, very good!) take Geen Line Metro to People's Square Station (People's Park, also good underground Fake Market!) = 5 stations, Go to NanJing Road toward Huangpu River. Metro Price (2011) 4-5 Yuan/person.
ALWAYS keep Metro/street Map with you! ALWAYS keep Business Card from your Hotel (to show Taxi Driver if lost) ALWAYS use Turquis Taxi, or pay tooo much.
