I just remember swarms of people and it was almost like a race reaching the top. Once you get to the top, there is a wall where everybody wanted a photo of. I think we tried a selfie but all you see are people in the background. I don’t think I can do this trek now if I had to do it again. Once is quite enough for a small town girl that doesn’t like highly populated areas. There are parts of the wall more remote with less people but it might be hard to get to. Do your research. Recommend going low season if there is one and to earlier in the morning! Best season to go is Autumn so you can see the beautiful leaves and get some good photos if the smog isn’t too thick. Good luck.
