10 Lomo up a wall
A trip to Beijing without visiting the Great Wall would be a disappointment. Taking the cable car up to the top is for wimps. Persuade your comrades it's the best way up then spend 20 minutes staggering up the steep stairs (don't forget to apologise at the top). Unbelievable view, you can only imagine how many workers suffered building the entire wall. Uninteresting note you can get a decent mobile phone signal at the top the Great Wall. On the way down prepare for the shop keepers selling all manner of souvenirs - t-shirts, fine rugs, masks, Mao caps, even the massive pipe that bloke is smoking. Once you start talking be prepared to buy or run as they chase you with more offers.
