These people hidden in every corner of the world——
They may be brightly dressed white-collar workers during the day; they may be taxi drivers who are happily grabbing taxis; they may be an ordinary gas station employee you see when passing by a gas station; or they may just pass you by.
After taking off this outer shell, they become night walkers in the darkness, jumping over the dotted buildings in the city to serve you. Even if they jump down from a tall building in the next second, they are still neat and clean.
Here, we call them professional runners.
