When we feel hungry, we can take out our phones and order some food easily. When we need to take a taxi, we can also use our phones to book one. It's so easy. But what will happen to the old who don't know how to use a smartphone?
With the development of technology, our lifestyle has been changed a lot. Lots of things can be done through the Internet, such as shopping, buying tickets and so on. New apps are easy for the young, while they are difficult for the old. Now China has come up with several ways to solve this problem. Everyone should take actions to overcome this "digital gap" (数字鸿沟).
Sometimes we only need several minutes to learn something new, but maybe it costs old people hours or even a few days. Next time when the old need help, we should be patient with them and never forget what they've done for us.
