China's appeal is difficult to overstate. Beijing draws visitors with its imperial history, from the Forbidden City to the sweeping stretches of the Great Wall. Shanghai offers a world-class food scene and one of the most iconic skylines on the planet. Xi'an is home to the famous Terracotta Warriors, Chengdu is the place to see giant pandas in their natural habitat, and the karst landscapes of Guilin rank among the most visually stunning scenery anywhere in Asia. Few destinations offer this level of variety within a single trip.
