In today's rapidly developing society, I believe that many people will choose to go out for fun and have a look in the outside world. In general, many people will choose green leather cars. In the previous green leather cars, I believe that everyone will have seen some scenes. Some people will sell some small toys on the train, and some people will sell lunch boxes on the train. However, few people will sell lunch boxes on the train now. The journey is long and bumpy.

The speed of the train is not particularly fast. Many times, I want to go to a place by train for a long time. On such a long train, the bumps along the way make many people give up choosing a box lunch, because the bumps along the way make it difficult for them to have an appetite to eat these things. Therefore, under the current social development, few people will go to the train to buy a box lunch, because there is no big appetite. The eating experience is not good.

Now the food on the train is not only unpalatable, but also very expensive, and the price/performance ratio is not as good as we thought. Moreover, most of the above ingredients are not particularly fresh, so few people will eat on the train, unless they don't bring their own food and when they are hungry, they will choose to buy a box lunch on the long-distance train to fill their stomachs. Moreover, on the train, once the box lunch is not sold on the same day, it is difficult to keep it. If it is thrown away, it will lead to food waste, which is a bad behavior. However, if it is not thrown away, the food will deteriorate after a period of time, and it will not be edible at that time. Therefore, eating on the train is a bad experience, so many people do not choose to eat on the train, and fewer people eat slowly, thus the box lunch will slowly disappear on the train. Ready-to-eat food replaced box lunch.

Why didn't anyone bring their own food before is because there was nothing to buy next to the train station, but it would be messy and unsanitary to bring food from their own homes. Therefore, in the past life, people would rather buy food on the train than go out to buy it themselves or bring it from their own homes. However, with the development of society and the progress of science and technology, ready-to-eat food has gradually entered people's lives, and now there are supermarkets or food outlets inside and outside the train station, so people will not worry that they can't buy it. Moreover, it is much healthier to buy this kind of ready-to-eat food outside than to buy a box lunch on the train, and it is also very convenient.

In fact, we have to believe that if we don't keep pace with the progress of the times, then we will definitely be abandoned by the society in which we live now.
