yeah yeah~ u must get ready for the ordeal when it comes to the rush hour ( even by subway or taxi, isn't it? )
and what BaoLe said is just a familiar phenomenon that the public transportation system will change some goddamn bus routes periodically... don't count on the subway, or even not to the metro line 3 and 4~ well, u may say it's more faster and not so crowded ( not crowded? don't you get the experience when taking it during the 7:30 A.M ~ 9 A.M.?) compared to those buses~ but metro is metro, u know, its stops are so limited that actually you still gotta go to the place you want by foot when getting off~
i get some methods of my own to deal with such pain (well, maybe u will laugh at me

):
by bicycle, if the destination ain't very far from where u r, i suggest u go their by bike~ but make full preparation before starting your journey and just as DragonAss and BaiLe, take a map with ya~
by bus, except when in rush hour, why not? also, here's a URL:
http://bendi.iask.com/ and after you type the destination you want to go and the location where you are, it will exactly show you how to go there by bus between the two places including the several different bus routes, quite easy for you, right?( say goodbye to maps~

)
the metro line and taxi is the last choice for me to take when in some extreme situations...
