Other pre-modern Chinese names for Tibet include Wusiguo (Chinese: ; pinyin: Wusiguo; cf. Tibetan dbus, U, [wy]), Wusizang (Chinese: ; pinyin: wusizang, cf. Tibetan dbus-gtsang, U-Tsang), Tubote (Chinese: ; pinyin: Tubote), and Tanggute (Chinese: ; pinyin: Tanggute, 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: ; traditional Chinese: ; pinyin: Tubote) 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]

Who fought to revive the term Xizang?
