Gampo, wishing to obtain a second wife from China, sent his ambassador to Emperor Taizong (627–650) of the Tang dynasty for one of his daughters. Taizong rejected the king's proposal, considering Tibetans "barbarians", and announced the marriage of one of his daughters to the king of Duyu, a Hun. This infuriated Gampo, who mounted attacks on tribal areas affiliated with the Tang dynasty and then attacked the Tang city of Songzhou. Telling the emperor that he would escalate his aggression unless the emperor agreed to his proposal, Gampo sent a conciliatory gift of a gold-studded "suit of armour" with another request for marriage. Taizong conceded, giving Princess Wencheng to the Tibetan king. When Wencheng went to Tibet in 640 as the Chinese wife of the king (known as "Gyasa" in Tibet), she brought an image of Sakyamuni Buddha as a young prince. The image was deified in a temple originally named Trulnang, which became the Jokhang. The temple became the holiest shrine in Tibet and the image, known as Jowo Rinpoche, has become the country's most-revered idol.
