Why was the name of the first store called worry-free grocery store?
In fact, at the beginning of the story, the essence of the whole story was directly expressed through the words of the store owner. He said that children have no worries, and some of the problems they think about are just because the problems themselves exist. On the contrary, adults are always worried because they need to think a lot, but even if they get the answer, adults can't be happy. And strictly speaking, "worry-free grocery store" is actually called "worry-free grocery store"
Secondly, the grocery store is the core of the story.
If this store is changed to another name, I will feel lacking, because in the process of people's growth, there will always be more and more troubles, and there is no way to get a reasonable solution. On the one hand, it is limited by our age, and on the other hand, it is because we always lack some necessary knowledge in the process of growing up, and we need to obtain this knowledge from the outside world, but in the meantime, we need to invest a lot of time and energy and make some difficult choices.
Third, how do you view the achievements of this novel?
