What does Han Han want to say at the end of ideal city?

Close to reality and profoundly reflect the distorted life of modern people.

I thought the ending was to arrange for them to leave the city, but unexpectedly, it described that the city was plunged into an extremely absurd disaster, and crazy people made crazy behaviors. However, "I" knew that everything would be back to the original state after this night, and life would still be the same.

I understand once again that the so-called ideal city is just a microcosm of a large and medium-sized country. No matter how ridiculous it is, no matter how ridiculous we are, we still can't escape from it, and we can't extricate ourselves from it. We can only go on like this, even if we don't know where we are going. Life is so unstable, I don't know what will happen suddenly, but we can only walk like this.

However, there is still a sentence that I feel very emotional and like: we always like something for a moment, and then spend many years interrogating ourselves why we like it.
