Guide: Feel free to ask me anything on today’s Great Wall tour.

Tourist 1: How long is the wall?

Guide: Ah, the most popular question! If we’re only talking about the parts from the Ming Dynasty, it’s about 8,850 kilometers long. This makes it the longest wall in the world.

Tourist 2：Wow, that’s amazing! Why did the ancient emperors build the wall?

Guide: The main reason was to protect their part of the country. As you can see, it’s quite tall and wide. As far as I know, there are no other man-made objects as big as this.

Tourist 3: Is Badaling part of the Ming Great Wall?

Guide: Yes, it’s the most famous part.
