In recent years, with the development of technology, many popular apps(应用程序) have been produced. These days, an app has caught great attention. It is Douyin, a video sharing app. Douyin first appeared in 2016. Now it is many people's favorite app, especially the young.
With Douyin, users can record videos, edit(编辑) them and share them online. It is very easy and interesting. We can share our videos with our friends with just a tap on the mobile phone screen. What's more, it's a great way to spend our free time by looking through those funny videos.
However, every coin has two sides. The app also has bad things. On the one hand, some people spend long hours on the app, which is bad for their health. On the other hand, users can also find some bad things on the app. Such thing is unhealthy and unsuitable.
In my opinion. Douyin should check the videos before they are uploaded (上传) in order to keep a healthy environment for its users. Douyin is not good for teenagers. We should not use it too often.
