Beijing is justly famous for the treasures of the Forbidden City, Tian'anmen Square, the Ming Tombs and Great Wall. And Xi'an has its 6,000 buried terra cotta warriors. Then there are Guilin's karst peaks and shopping in modern Shanghai or Hong Kong. China is "big"! And there are "hidden treasures" in more remote spots. The spectacular mountains of the SW provinces boast over 3 dozen ethnic tribes. The far west is home to a fascinating mix of formerly nomadic Gobi desert cultures, their monuments, oases and the terminus of the Silk Road.
