Tibet (Xīzàng) is an autonomous region in the People’s Republic of China, located on the high-altitude Tibetan Plateau. The name literally combines 西 (xī), meaning 'west', and 藏 (zàng), a historical term referring to the Tibetan people and their culture—derived from the older Chinese name for central Tibet, Ü-Tsang. Though 藏 can also be pronounced 'cáng' (meaning 'to hide'), in this proper noun it is always read as 'zàng'.

Xīzàng is widely recognized for its unique Buddhist traditions, breathtaking landscapes—including Mount Everest and vast grasslands—and rich cultural heritage. It is commonly used in geographical, political, and travel contexts, such as 'Xīzàng Autonomous Region' or 'traveling to Xīzàng'. While historically and culturally distinct, it is officially administered as part of China’s territory, and the term carries strong regional and administrative connotations.
