"好的结局是幸福的，坏的结局是悲惨的。这就是小说的意义。"

Simplified Meaning:

In stories, good people often get happy endings, while bad people end up with sad or bad outcomes. This is a common way stories are told. Imagine a movie where a kind hero saves the day and gets rewarded, while the villain gets caught and punished. That's how fiction usually sets things up: to make us feel satisfied that the good are rewarded and the bad face consequences. In real life, things aren't always so simple. Sometimes good people go through hard times and bad people might not always get what they deserve. But in stories, this clear-cut ending helps teach lessons and gives us hope. When reading a book or watching a movie, you can see this pattern and understand that it’s a way to keep the story clear and meaningful. Applying this idea, we can strive to do good, knowing that in fictional worlds, at least, goodness brings happiness.
