Which travel book should I buy when going to Taiwan?

Update 1:

THX~^^ When I was traveling in Taiwan last month, I bought a travel book (map) smaller than A5 at the local 7-11. It seems to be called "MRT Tour", and it's only about NT$148, so it's very convenient! Ximending, Shilin Night Market, Xiahai City God's Temple, and Tamsui are all nearby the MRT. They are very convenient, so don't worry. Ximending: Similar to Mong Kok, you can see Taiwan’s current culture. Shilin Night Market: People who go to Shilin usually go to Miramar (Ferris Wheel). There are free buses! Xiahai City God's Temple, Tamsui: They are both Tamsui lines anyway, so just put them on the same day. As for what other attractions there are, you can go to the following website: okgo/buty/taipei. It has a complete introduction, address and directions, which is very useful! I have this copy, it’s very useful! You can find them in major bookstores in Taipei.
