Who traveled on the Great Wall of China? Did they ride on specific animals? What did they bring?

Please give me the answer to these questions. Its for my Social Studies project and its due sometime soon. I would greatly appreciate it if you could find the answer. My project is on the Great Wall of China and I need this kind of information to get a good grade. I have been working on this topic for sometime now, I've started my handout and I'm almost done my facts and notes on my topic. I just have the rest of those things and my report and my presentation with a script. Once again, I would love to hear the answers to these questions to get the grade I'm looking for. Thank you and have a good day!
Sincerely,
Scarlet
