The Advantages and Disadvantages of Digital Life
Digital life has changed our daily life greatly, bringing both good and bad sides.
On one hand, digital technology allows us to pay easily with smartphones and study online anytime. It also helps us stay connected with friends far away. On the other hand, some people get addicted to phones, which makes them ignore real-life interactions. What’s more, too much screen time is bad for eyes.
We should balance digital life and real life, using technology wisely to make life better.

Dear Peter,
I’m glad you’re curious about digital life in China! It’s really convenient and has become part of our daily life.
We rarely carry cash now—mobile payment apps like Alipay and WeChat Pay let us buy things with just a scan. Shared bikes and food delivery apps make our life easier. We also use online learning platforms to study after class. However, we’re told not to spend too much time on phones.
If you come to China, you’ll love this convenient digital life!
Yours,
