About Liu's supernova age! Ask the master to answer!

1. The open ending actually means that the initial chaotic period has passed and a new world order has been gradually established.

The purpose is, of course, to let those young children spend endless tossing on the right road. When young intellectuals went to the countryside, they sent those children who were making trouble in the city to the mountains for construction. It is better to give them a new world of exploration and construction than to let them toss about. The freshness of the new world will arouse the curiosity and fighting spirit of American children. As for what I saw, it's hard to say, but at least for the United States and China, it's almost a reshuffle. You can't take everything with you? This should actually be easy to understand. Chinese civilization is very homesick and misses the past. Only when you have a home can you have the motivation to struggle and forge ahead. You don't want them to take everything away, just to make the children in China forget their homeland and indulge in the rich fun of the United States.

3. Well, you really don't need to write carefully. It just expresses that the children did not disappoint the adults, and finally created a brilliant civilization. There is no need to say more about sad things. History must be tragic. Readers can use their brains to think about what it will be like.
