How to evaluate Liu's science fiction novel The Wandering Earth?

The consistent scientific rationalism and realism in Liu's numerous works have really shaped the values and world outlook of a large number of young people in China and influenced their behavior patterns imperceptibly. The Wandering Earth contains some core motifs in Liu's works.
