I want to write 490 words on Mars.

In my childhood imagination, there were thousands of strange and interesting ideas from Qian Qian, but the most interesting one was emigrating to Mars.

Now, the population of our earth is about 6.3 billion, which is too much! Moreover, China has a population of1300 million, so we often think that it would be great if 40% of people on our planet immigrated to Mars!

On Mars, scientists first dropped an electronic ball, and Mars became as rich as the earth. Then drop an electronic ball, the sea and trees are deformed, and then drop the next one, and all countries will immediately divide their borders. On the other side of Mars, "People's Republic of China (PRC)" became "People's Republic of China (PRC) of Mars" and "United States of America" became.

Then, scientists dropped an electron ball, and Mars immediately had an atmosphere, an ozone layer and gravity. Another electronic ball was dropped, and convenience stores, shops, markets and parks appeared on Mars ... Many, many things, and some people were moved to Mars. Scientists also dropped an electronic ball between Mars and the Earth, which turned into several tunnels. As long as you enter the tunnel, you can shuttle between the earth and Mars. And every city has an entrance, which will instantly move into the tunnel, reach the end of the tunnel, and instantly move to the destination.

Although this is only a small imagination, I believe that it can be achieved as long as you work hard.
