The Metro and the City is an example of the co-habitation of two entities. The entirety of the metro line, from its stations to its tunnels and shuttles, are a closed system. From the point of view of the city, passengers are transported from one red dot to the other, as if it were magic.

捷運與都市為一種二元的共生關係。捷運系統裡的捷運站到地道和車廂都是一個封閉的系統。從都市的角度，乘客會從一紅點消失然後神奇的從另一紅點出現，猶如魔法一樣。
