    The sun is going to expand into the orbit of Mercury (水星) according to scientific calculations, which will result in the entire Earth catching fire, destroying all life. In order to survive, the United Earth Government prepares 10,000 giant engines on Earth to drive it away from its original orbit. The whole trip is expected to last 2,500 years.

This imaginative tale is at the heart of the science-fiction movie The Wandering Earth. The original novel was written by Liu Cixin, one of China’s most outstanding science-fiction writers and a prize winner of the Hugo Award in 2015 for his novel The Three-Body Problem.

Perhaps thanks to Liu’s fame, as well as the huge marketing efforts of the movie team, The Wandering Earth posted ticket sales of 670 million yuan when it was shown on the first day. More importantly, The Wandering Earth is the first “made-in-China” science-fiction movie on the big screen, as the director, Guo Fan, is also Chinese.

As a fan of Liu, having read almost all of his science-fiction books, I should mention the movie follows a rather different form from his novel. Actually, it only borrows from the novel the idea of the Earth having to escape the solar system. That’s just the point. It means Chinese movie production teams have grown enough to develop new ideas on the creative basis of science-fiction writers, while the writers are willing to work together with movie productions so that the film results in the best possible performance.

Liu may be a highly regarded science-fiction writer in China, but he is not the only one. There are many writers with rich imaginations, and their works can be adapted into movies, too. Someone has predicted that 2019 will mark the starting year of success for Chinese science-fiction movies. Only time will tell whether that prediction will come true. But if more professional movie teams and creative writers could work together, we can certainly expect more success for the domestic (国内的) science-fiction movie industry.
