Wouldn't you just be another cog in the crowd machine though? Crowds aren't always predictable (or even the density of one), but I do have a short-term solution in case you (or anyone) finds him/herself in China-take the stairs. Although I mentioned it in the China forum somewhere, as long as escalators are up and running, stairs will be your pal.

Another note about scrums; as much as I would prioritize eating when I travel, a queue at a restaurant is never worth it for me. Unless someone else (someone with me at the time) is footing the bill.
