? I think it's a wandering earth. However, this plan is gradually improved and then implemented. The first step is to build a planetary engine to stop the earth from turning. The second step is to speed up the earth's escape speed again and fly out of the solar system with a propeller; The third step is to start interstellar wandering, continue to accelerate and fly to proxima centauri; Step 4, arrive near proxima centauri and adjust the direction and speed of the engine; Fifth, slowly push the Earth into proxima centauri orbit and become one of its satellites. It is estimated that the whole project will take 2500 years and require the joint efforts of 100 generations.

? Three development directions of China films in the new era: critical realism, science fiction theme and literati films. The first two films have already started, and they have made a good start. Now they are waiting for the literati films. Critical realism films rely on censorship and grading system, mainly censorship, and Dying is the best example. The theme of science fiction depends on the foundation and system of the whole film industry in China. We need to build our own science fiction film universe based on the literary works created by a group of outstanding science fiction writers represented by Wei Liu. There are "Marvel Universe" and "DC Universe" in Hollywood, and we should also have our own "Big Liu Yuzhou". There is no denying that Liu is indeed an unavoidable name in China's sci-fi, and the wandering earth has already opened up our own way; As for the literati film, it's up to you.

The birth of The Wandering Earth realized Liu's dream and made people see hope. Ji, the founder of the Future Affairs Administration, said: "The Wandering Earth's success in film production has broken a lot of' disbelief' and let filmmakers and investors see the height that China's science fiction movies can reach today." A number of people in the industry said that the film The Wandering Earth proved that we can make a good enough sci-fi blockbuster of heavy industry, which "will probably become a landmark work in the process of film industrialization in China".

The Wandering Earth's greatest contribution to China's movies is to open up a new situation of China's sci-fi movies, open up a road of China's sci-fi movies, boost the morale of the market, audience and filmmakers, and lay a solid foundation for the development of China's sci-fi movies.
