The family is second only to Indo - European in terms of the number of native speakers . The Sino - Tibetan languages with the most native speakers are the varieties of Chinese (1.3 billion speakers), Burmese (33 million), and the Tibetic languages (6 million), but many Sino - Tibetan languages are spoken by small communities in remote mountain areas and as such are poorly documented . Unlike Western linguists, Chinese linguists generally include Kra--Dai and Hmong - Mien languages within Sino - Tibetan . </P> <P> Several low - level subgroups have been securely reconstructed, but reconstruction of a proto - language for the family as a whole is still at an early stage, so the higher - level structure of Sino - Tibetan remains unclear . Although the family is traditionally presented as divided into Sinitic (i.e. Chinese) and Tibeto - Burman branches, a common origin of the non-Sinitic languages has never been demonstrated . Several links to other language families have been proposed, but none has broad acceptance . </P>
