How to get to Quanqian Street to Shantang Street by subway from Suzhou Bus Station?

Do you refer to Guanqian Street and the Northern Square Bus Station near Main Railway Station? If yes, you may take bus line 8 to Leqiaobei Station, and walk north for about 500 yards to Guanqian Street. You can take metro line 2 from Main Railway Station to Shantang Street directly. :)
