escalator
In the picture, there are two men on a escalator. You can see the equipment set in places such as department stores and MRT stations. It's a thoughtful design for people to get upward and downward with less effort. Also, it provides efficiency for busy and lazy people. Although some argue that it could be dangerous to hurt people when they accidentally fall on the stairway, many experience its benefits for most of time.
The escalator in the picture is long and deep. It saves time to go down from the other end above through a escalator. There's a rule when people take the escalator. It's polite to stand on the right side and make the room for someone who can move through on the left. For a security concern, people are not allowed to run or jump on the moving stairs. I enjoy taking the escalator. I like the feeling it moves me from up and down in a stable way.
