Different people go to work in different ways. Some people go to work on foot because they live very near. Some people go to work by car because it’s fast. In some big cities, lots of people like to take the subway. It’s fast and cheap. You can buy your tickets(票) on your phone. How can you find a subway station? You can see different logos in different cities. In Beijing Subway Station, you can see the logo , and you can see the logo in Shanghai, and in Wuhan. When you see those logos, you can find the subway station nearby. During the time when people go to or come back from work, the subway is always crowded(拥挤的). It’s called the rush hour. So it’s not a good idea to take the subway during rush hours(交通高峰期).
