This may be because different countries have different cultural psychology. The people of China have a long history and civilization, so they cherish the past time. Isn't our slogan to realize the great national rejuvenation? Because of the prosperity of ancient times, many people returned to ancient times. Another reason, I think, is that technology limits imagination. Of course, you can say that China people don't imagine the future as much as the United States.

Americans want to shoot the future because the United States is an immigrant country, and its own history is 100 years. There's really not so much to shoot. In addition, Americans are praised for their positive and optimistic national character. Uncle Sam likes to look to the future, hoping that the future will be better than modern times. The advanced level of science and technology in America is also an important factor. Also, the United States has a good imagination and can make logical movies.

South Korea's future people have crossed over to the present because Koreans pay more attention to modern life and may want to see a different life in reality.
