In the past, people lived in old houses surrounded by green lawns. In the past, neighbors were like brothers, neighbors were like friends, and people who were not related used to go back and forth with each other. In the old days, the whole village had only one television, and in the evening everyone came to watch it, excitedly crowded like a festival. Although it was a black-and-white TV, the picture was sometimes not clear, but the whole village was surrounded. Some people sat, others stood; young children sat on their mother's lap; older children looked through the gap on their tiptoes, standing all over the house, but it was not cramped; the atmosphere was bustling and jubilant. Now, living in a high-rise building in a magnificent city, there is no lack of material comforts. But even though the door on the lower door must be closed tightly, sitting in the house is still restless. There are times when even we ourselves cannot enter the security net, which includes the anti-theft door, the camera, and the security net that surrounds the whole building. People are not as friendly as they were in the past.
