Besides sleeping, we can also read books while taking the subway, which is also the most common way to kill debris time. For example, we can look at the morning paper and some magazines with few words.

Because when we browse words and pictures, our brain will think subconsciously and our thinking will gradually become clear. Interesting articles can also broaden our knowledge and know more unknown things.

However, modern people seldom read newspapers. In my family, my grandfather usually reads it once and extracts the more important contents and writes them down. In fact, the contents in the news are very useful, and both staff and students can learn knowledge in this leisure time. After all, "use books, hate less"!

Step 2 play with your mobile phone

In fact, no matter where you go, it is extremely bad to hold your mobile phone in your hand. But you'll be fine if you take the subway. You can make full use of your spare time to understand current events or read some funny jokes.

If you take the subway in the morning, playing mobile phone can just wake up your confused brain. You won't just play games on your mobile phone all the time. You can also brush Weibo and visit friends, which are very good ways to use the debris time.
