Other pre-modern Chinese names for Tibet include Wusiguo (Chinese: 烏斯國; pinyin: Wūsīguó; cf. Tibetan dbus, Ü, [wyʔ˨˧˨]), Wusizang (Chinese: 烏斯藏; pinyin: wūsīzàng, cf. Tibetan dbus-gtsang, Ü-Tsang), Tubote (Chinese: 圖伯特; pinyin: Túbótè), and Tanggute (Chinese: 唐古忒; pinyin: Tánggǔtè, cf. Tangut). American Tibetologist Elliot Sperling has argued in favor of a recent tendency by some authors writing in Chinese to revive the term Tubote (simplified Chinese: 图伯特; traditional Chinese: 圖伯特; pinyin: Túbótè) for modern use in place of Xizang, on the grounds that Tubote more clearly includes the entire Tibetan plateau rather than simply the Tibet Autonomous Region.[citation needed]
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What name for Tibet most clearly includes the entire Tibetan plateau?
Tubote
