Nowadays, we have already reached a period science and technology are highly developed. In 2016, a new App, Tik Tok, (come) into being, which can help people share interesting things with others. However, more and more teenagers are so crazy about Tik Tok that they are (lose) in it. There is no doubt that Tik Tok has a negative effect on our teenagers.
(luck), the Chinese version of Tik Tok is introducing a "teenage mode" which will limit the amount of time children under age of 14 spend on the short-form video app 40 minutes a day. It's suggested that all Douyin users under 14 register for the app by using (they) real names. Besides, Douyin will also be (available) to those teenagers between 10 p. m. and 6 a. m. to protect their physical and mental health.
