Ok miantian. Let's take our time.
So Higher in this thread you said you said your client was patched at 3.3.5.a and you were at step 3.
So first of all, start your client (not via the launcher but the wow.exe file). When you arrive at the login screen check the bottom left of your screen and make sure you see 3.3.5.xxxxx(or it might be 3.3.5.a either way) . If that's the case it means you patched successfully, if that's not the case you gotta install the missing patches.
So your client is at the right version and now it is time to apply the fix to play on chinese servers. so
Download http://www.gamefront.com/files/20318169/TOwowCN126.96.36.19930.rar and extract it into your /wow folder. To do so simple copy the archive in your wow folder, right-click it and select extract here.
Now you'll notice the archive extracted a new folder called TOwowCN188.8.131.5230, so go into this folder. Now execute TOwowCN184.108.40.20630.bat (or TOwowCN220.127.116.1130 if you don't see extensions) and follow the instructions.
Once in the batch you'll have some menus. You'll choose the PATCH option, then select the local of your client (enUS for us client, enGB for UK). Then let it run till it says it's done.
Then you can play the game.
