I remember that when we didn't have a mobile phone, we could only make calls on the landline. At that time, not every household had a landline. Those families who can have fixed telephones are in good condition. In the past, I could only buy tickets at the railway station, and I didn't know when to queue up. Even if we don't have the tickets we want, we often have to buy tickets long in advance. At that time, we will go to the store to buy food. At that time, all social information was basically from TV and newspapers.
It's different now. Times have changed. In recent years, China has developed rapidly, which has brought great convenience to life in transportation and commerce. After these new developments, it is followed by the development of network. The mobile phone extended from the network has undoubtedly brought great convenience to people's lives. You can pay attention to the news all over the world anytime and anywhere. There is no charge for taking the subway. You can move your fingers. When you buy a ticket, you can buy it on the app, watch the weather forecast anytime and anywhere, order take-away food on your mobile phone, order vegetables, and soon someone will deliver it to your door, take photos, and record beautiful moments with video.
In the past, I could only watch TV dramas on TV, and I couldn't find a few channels. Now you can watch it directly with your mobile phone. There are many kinds. You can also play games on your mobile phone, which adds fun to your boring life. Of course, the most practical function is video calling. Children can go out to work, watch videos anytime and anywhere, and learn knowledge from their mobile phones. Many textbooks have electronic versions, which can be downloaded and studied directly. Where do you want to travel?
