阅读短文,回答问题Do you know which social app is popular with Chinese young people now? "Short videos" are certainly the most popular. A large number of young people use Tik Tok (抖音) and Kuaishou. They think it is fun to share their lives by short videos, while others have other purposes as well.
A t2-year-old user named Elsa has about 2. 7 million fans on Tik Tok. The girl has shared her dancing studies on Tik Tok since last July. One of the videos won her about one million tans. "I feel really glad to share happiness with people by short videos." said Elsa.
To some other young people, they use short videos to have a quick look at the hot programs. "Because I don't like to spend many hours watching a whole program, I hate waiting for a program to end, and I prefer to watch short videos of wonderful parts of hot programs," said Wang Zhihao.
However, some young people feel bored with short videos. "Killing time is the main reason for me to watch short videos, and many short videos are almost the same, so I think they are not so useful or interesting. What's more, I really don't like the videos about strange and dangerous things," said Wen Nan, another college student.
Recently, something else has appeared. Some videos are telling people what commodities are worth buying. Some short videos even sell bad commodities, and it is hard for customers to get their money back. So we should think twice before we want to buy the commodities by short videos.
