Everyone has a dream, so do I. I often dream about a modern and colorful city. In my mind, the city in the next fifty years is on Mars. Here, we will build the high buildings, the beautiful school, the colorful place such as parks, student's library, exhibition room, etc. At that time, we will use another energy instead of electronic energy, the vehicles will be a little change. The relationships of people become nicer, the friendships will be cleary, everything will be better. People will still live after a thousand years, out of old. There will be no dangerous disaster such ass Covid-19, Sars, etc. People's Life will be better than now. Thank you for your reading <3!
