'Wandering Earth' was a science fiction adaptation of a novel.
The general content was to save the earth, and the father and son were both fighting in places where they could not see each other.
Even with the help of global technology, it could not change the fact that earth had crashed into Jupiter, and humanity was in danger of being destroyed as the countdown went on.
At a critical moment, the father of the astronaut did not want to abandon his family on earth, and he did not want to escape the Solar System by piloting the space station known as the 'human spark'.
Instead, he headed to the space station to crash into Mars, using his life to ignite the hydrogen on Jupiter's surface, causing the explosive shock waves to push earth away from Jupiter, thus avoiding the outcome of earth colliding with Jupiter.
What moved the audience was not the outstanding special effect of the movie. It was more of a shock, a shock to the soul!
