Most of western China is less developed, less polluted, sparsely populated, home to dozens of minority nationalities, and geographically comprised of high plateaus, mountain ranges, and barren desert. This makes the language, cuisine, and customs also vary greatly compared with Eastern China. For me, this is a really interesting, vibrant, and under appreciated area for Western tourists. So, this section presents the other half of China, but more importantly, encourages visitors to see more than a few big cities; get off the beaten path and travel west!
