These days, they use so much pesticide that when I feed the children, I have to soak the vegetables for at least two hours. - Liu Cixin

Everyone is afraid of something. The enemy must be, too. The more powerful they are, the more they have to lose to their fears.

Look at them, the bugs. Humans have used everything in their power to extinguish them: every kind of poison, aerial sprays, introducing and cultivating their natural predators, searching for and destroying their eggs, using genetic modification to sterilize them, burning with fire, drowning with water. Every family has bug spray, every desk has a flyswatter under it… this long war has been going on for the entire history of human civilization. But the outcome is still in doubt. The bugs have not been eliminated. They still proudly live between the heavens and the earth, and their numbers have not diminished from the time before the appearance of the humans. The Trisolarans who deemed the humans bugs seemed to have forgotten one fact: The bugs have never been truly defeated. A small black cloud covered the sun and cast a moving shadow against the ground. This was not a common cloud, but a swarm of locusts that had just arrived. As the swarm landed in the fields nearby, the three men stood in the middle of a living shower, feeling the dignity of life on Earth. Ding Yi and Wang Miao poured the two bottles of wine they had with them on the ground beneath their feet, a toast for the bugs.

Of all the unexpected things that might interrupt Chinese science fiction’s development, social unrest has to be the most worrying. I once told readers at a conference that science fiction is the product of leisurely and carefree minds. No one agreed, but I was telling the truth. Only when our lives are stable and quiet can we allow the universe’s catastrophes to fascinate and awe us. If we already live in an environment full of danger, then science fiction won’t interest us. In fact, two of the last three bursts of creative progress that Chinese science fiction underwent were cut short by social unrest, which is lethal to the genre.
