One possible version: The Great Wall is very famous in the world. It's one of the greatest man-made wonders of the world. It's made up of huge stones. It's about 21,196 kilometres long, with a history of more than 2,000 years. It looks like a huge dragon. It took millions of ancient Chinese people all their lives to build it. In my opinion, it is the symbol of China. We can also say it stands for China. We should protect it. I think people all over the world should go to visit it. It's so wonderful.
