8．If you live in a big city，there are many things to drive you crazy on your daily route，and it's not just overcrowded subway trains．
Vicky Zhao is a mainlander working in Hong Kong．For her，one thing she can't put up with is people standing on the wrong side of the escalator（自动扶梯） in subway stations．"Escalators help us move faster and save time．It isn't a place to rest，"the 24-year-old says．"I often see tourists block the way with their suitcases or chatting on the escalators during rush hours．It annoys me to no end．"
Admitting she is not the patient type，Zhao says things are much better in Hong Kong than in cities on the mainland where"stand right，walk left"signs are often ignored．
The logic behind the"stand right，walk left"escalator etiquette（礼仪） seems obvious．Even though you may want to catch your breath while you're transported up or down，you should still consider others and leave enough space for people in a hurry，so that they can run and catch the train．
Many cities'escalators，including London's and Beijing's，use the"stand right，walk left"system to speed up the flow of people．（Australia is an exception and you should stand on the left side instead．） But some cities discourage people from moving on escalators out of safety reasons．In Hong Kong's subway stations there are regular announcements asking people to"stand still"on escalators．Even so，most people in this fast-paced city observe the"stand right，walk left"etiquette．
But the people who stand on escalators defend themselves by telling the walkers not to be so impatient．The BBC quotes one stander as saying："If the person is in such a rush，why not just take the stairs？Even when the escalator is packed and there's nowhere to move，I see these same people complaining about not being able to pass．"
Whatever the escalator etiquette is in the place you live or visit，do what most people are doing and always be mindful of others：leave enough space between each other，don't stay at the end of the escalator，and if someone is blocking your way，a simple"excuse me"is enough．
