Taipei Main Station is a transportation hub in the capital of Taiwan. Traveler can take trains, high speed rail, Taipei Metro, Taoyuan Airport Metro, and even highway buses to almost every cities in Taiwan here from the station. On the other hand, underground shopping streets also lie between structures of different transportation facilities, connecting with each station providing many kinds of foods, drinks and gifts.
With such amounts of different systems all together in this specific area, route to each station would be complecated. That's why the station is so called the biggest maze in Taiwan. To solved this multi cache, hunters should pass through some area of this maze. I would try my best to make things clearer for hunters to get through.
Luckily, underground structures are divided into different areas with their own letter code, such as M for the metro, R for ZhongShan Metro Mall, Y for Taipei City Mall, and so on. Entrances of each area have their own number starting with the code, which helps travelers identify their current location. If you are not familiar with Taipei Main Station, you can refer to here for a detailed map.
