Wen Cheng Princess was a distant blood inferior of the Tang emperor. In 640, the Emperor Taizong conferred the princess title to a girl of his family with the surname of Li, 

and sent her to the Tibetan regime to become the queen of Srongtsen Gampo, the dominator of the area. Since then, the Tang Dynasty built a close friendship with the Tibetan regime. In the two hundred years, every new Tibetan king would send envoys to the Tang Dynasty for the emperor’s “conferring”. The princess, who was well-educated and brave, made historic contributions to the economic and cultural exchanges, as well as the close friendship and cooperation between the Han and Tibetan peoples.
