Nowadays, lots of APPs such as DouYin and Kuaishou are making a big difference to our own life. People often watch short-videos on them for fun when they are free.

　　However, it's not always good for people to spend too much time on the APPs like DouYin. Although they can make you happy or make you feel better, it's a waste of time. You can spend time on other things that make you smarter and happier. For example, if you are tired of doing math homework, you can listen to some English songs. It can make you relax, and it can improve your English level at a time.

　　It's not good for people to spend too much time on APPs like DouYin. People should learn more and improve ourselves so that they can make their life more colorful and wonderful.
