1 . Do you know which social app Chinese young people use a lot now?     1     Some users use Tik Tok (抖音) and Kuaishou. They think it is fun to share short videos about their lives, while others have other purposes as well.

A 12-year- old user named Elsa has about 2.7 million fans on Tik Tok. The girl has shared videos about her dancing studies since last July.     2     “I feel really glad to share happiness with people by short videos,” said Elsa.

As some videos are about the latest news, a group of users depend on them to get information. To some other users, they have a different purpose. “Because I can’t spend many hours watching a whole video and I’m not a very patient person,     3     I prefer to watch short videos of wonderful parts in programs,” said Wang Zhihao.

    4     “Killing time is the main reason for me to watch the short videos, but many are almost the same, so I think it is a waste of time. What’s more, I really don’t like the videos which show strange even dangerous things,” said Wen Nan, another college student.

Recently, something else has happened. Some videos are telling people what products are worth buying.     5     So they should think twice. Some short videos even sell bad products, but these sellers won’t let you get your money back.
