It is important to remember that Tibet areas consist of far more than just the Tibet Autonomous Region (TAR). Basically Tibetan area is divided into three big regions based on differences such as dialect and lifestyle, U-tsang,Kham and Amdo among which U-tsang is now referenced as TAR or the Central Tibet. Visitors who have never visited Tibet area are completely unaware of the existence of Amdo and Kham regions of the Tibetan Plateau, which are actually indispensable parts of whole Tibetan areas.
