Although they have been officially included as part of the Tibetan nationality, Chinese scholars have considered the Jiarong distinct for several decades. In 1957 the Chinese Academy of Science listed a population of 70,000 Jiarong. One linguist notes, "The Jiarong are within the cultural orbit of Tibetan Buddhism but speak distinct languages."
Sidabao Jiarong is part of the Qiangic branch of Tibeto-Burman. There are two main dialects of Sidabao: Ribu and Caodeng. Ribu further divides into "several quite different local varieties, such as Shili in Zamtang County, Rongan in Aba County, Ribu proper and Dawei in Barkam County."
One Chinese source claims the Jiarong "are a branch of Tibetans who moved in remote antiquity from Qungbu in Tibet to live in the Songpan Plateau of northern Sichuan." Buddhism arrived in Tibet during the reign of King Songsten Gampo (c. AD 605-650). It officially replaced the Bon religion and gradually worked its way to the extremities of the Tibetan world, including the area inhabited by the Jiarong today.
The Jiarong are looked down upon by both the Chinese and the Tibetans. "Those Jiarong in the towns hold no more than low-level clerical jobs, as they are generally poorly educated."
There is a revival of the ancient Bon religion in recent years among the Jiarong. For the past 13 centuries, Buddhism has been something of a veneer on ancient Bon rituals. The spiritism and black magic, still prevalent in Tibetan Buddhism, stem from Bon.
The few attempts to evangelize the Jiarong in the past met with some success. In 1934 missionaries listed 34 Jiarong believers. Another book from the 1930s lists a number of Jiarong Christians, but presently there is no indication of any believers among them. "Social ostracism of possible converts, and persecution to the extent of the placing of severe curses by the lamas, or poisoning through family members, are other hindrances to spreading the Gospel."
