First of all, we need to find the bus stop first. Bus stops are located almost everywhere in Taipei. And you will be able to see which bus stops at this bus station. 

If you look closer, you will be able to see the complete route of the bus. Some of the stops (like MRT stations) have their English name written below.

One thing to note is the direction of the bus. You need to see the "arrow" mark to know which direction the bus is going. And sometimes this can be quite confusing. It'll be easier once you get used to Taipei's road direction. =P

OK, you know where you are going. You have successfully give signal to the bus driver to stop and now..how are you supposed to pay the bus driver? You just need to get your EasyCard (yes, that MRT card) ready and..tap?? Wait a minute! There's another step that you need to see before you decide to tap or not. 

Oh no! Another bus sign and it's in Mandarin. O_o!

Basically bus fares in Taipei is divided by section (one or two), and this, affects when the passengers pay. When you step into the bus, check this sign out. If the sign begins with 上 you tap in the EasyCard when you get on the bus. If the sign says 下  you tap the EasyCard when you get off. 

If you paid when getting on and the sign changes to 下 during the journey, do not panic! (I was panicking a bit when that happened the first time though. I thought I saw the sign wrongly!). If that happens, simply tap again when you are getting off the bus because you have traveled through two bus zones.
