A new way of eating becomes popular with young people on the Internet. It is called mukbang. Starting from South Korea, mukbang means "eating broadcast（吃播）". The hosts live-stream（直播）themselves eating a large number of food online. At the same time, they talk with those who are watching them through the Internet.
In South Korea, it's not common for people to go out to eat by themselves. Dining is a social（社交的）activity, and people don't sit and eat alone（独自）. For those who can't eat with others, they'll stay at home to eat alone, but they still want to meet and spend time with people while eating. So they think of the idea for mukbang. In this way, they'll never eat alone again and they can even make a lot of money.
Now mukbang is popular in the world. People can share the happiness of eating and make friends through mukbang. It also helps people who have problems with food. By watching mukbang, those who always eat too much can satisfy their appetite（胃口）and those who don't eat enough can build their appetite.
