How to write 4 words of tour guide?

Hello, everyone. I am your tour guide. Today, I have the honor to visit our Chinese treasure-the Great Wall of Wan Li with you. We visited a part of the Great Wall, especially Badaling Great Wall. I hope you can have a pleasant day here.

The Great Wall is one of the seven wonders of the world. From the moon, it can also be photographed like a long winding dragon. It is really spectacular. It's only a hundred miles from Beijing to the Badaling Great Wall, which is made of huge stones and city bricks. The top of the city wall is paved with square bricks, which is very flat, like a very wide and wide road. In ancient times, five or six horses could run side by side. Piles more than two meters high along the outer edge of the city wall are arranged in rows, and there are watchports and shooting ports on the pilings for lookout and shooting. On the top of the city wall, there is a square platform every 3 meters, which is a fortress for stationing troops. When fighting, signals can be sent between the platforms.

Standing on the Great Wall and stepping on the square bricks under your feet, will you think of the ancient working people? These strips of stone weighed two or three thousand kilograms. At that time, there were no trains, cars and cranes, but they were carried up this steep mountain step by step by countless shoulders and hands. The Great Wall is the condensation of ancient people's blood, sweat and wisdom.

Isn't the magnificent Great Wall of Wan Li a great project in world history?
