I did exactly this 5 mins ago.
great minds think alike
But it's not helping me much tbh.. the tours are too expensive. I mean not too expensive for me (that too), but stupidly expensive for what they offer. Makes no sense.
That's tourism. Probably Chinese governement gets money in restoring the Great Wall (hopefully)
I still remembered My trip to Ming Tombs. There was helicopter tour to view the whole area in the air. For the same service, there was three different price. Cheapest for Chinese, double the price for Chinese from Hong Kong and Macau (China government has a different travelling documents for these people) and quadruple for visitors with passports from other countries
