During the Spring Festival, I watch a sci-fi movie The Wandering Earth with my friends. The movie direct by Guo Fan is very popular in China. It is set in 2075, where the earth is no longer safe to live. Unlike most western movies, the heroes do not give up the earth. Instead, they choose to save the earth by send it to another so-like system. I was deep impressed by the three generation of a Chinese family. They devote them to the mission. The movie conveys lots of Chinese values, but I think it is quite worth seeing it.
