Now everyone has a mobile phone with more and more functions, but gradually people forget its most common use.

During the Spring Festival, buses bound for the countryside are always very crowded. Noisy voices filled the narrow buses, and large bags of Chinese New Year luggage were piled on the ground. I stood on tiptoe and reached for the handrail, for fear that the driver would suddenly brake and make me fall. Standing next to him is a man in his forties. His clothes are not brand new, even with some dirt, and they don't look warm. He has been talking to people on the phone, just some simple words. I listened silently, and my eyes were a little sour.

"Mom, I'm in the car. I'll be right with you! . "

"I have eaten."

"My clothes are quite thick."

"Go after fifteen o'clock."

"I want to stay a few more days, too."

The man's tone changed from happy at the beginning to helpless, and finally hung up the phone slowly. Look at him carefully putting the outdated bar phone in his pocket. My heart is full of something. Looking around, most people in the car are playing smart phones. But no one calls home with a mobile phone. Some people will say, now that technology is developed, there are QQ and WeChat. Isn't it enough to have these softwares for family greetings? In today's society, people have other factors, either because of work or because of time. The affection in people's hearts is getting weaker and weaker, and there is less and less care for their parents. China's fine tradition and all the virtues of filial piety are also losing bit by bit.

Where has all the time gone? My parents were old when they were young. I have been working hard for my children all my life. Ladies and gentlemen, put down the dazzling software in your mobile phone, just dial the phone and let your parents listen to their own voices. This is the function of the mobile phone, so pick it up quickly!
