Most people's living expenses are only about 20 yuan a week, and a small *** is their living expenses for half a month, which is still very precious, and only people with slightly better family conditions will buy it for their children.

People born after 00, the material conditions are already quite good, basically smartphones, not only can **listen**, watch TV, and even watch live broadcasts on the Internet, which completely replaces the previous *** and mp4. Today's smart phones combine many functions such as ***, mp4, TV, **, etc., and the post-00s feel that it is a matter of course, but as long as people who have experienced it know how rapid the development of science and technology is, and how happy the days are now.
