Li Daozong
In spring 641, Taizong sent his cousin, Li Daozong, Prince of Jiangxia, to accompany Gar Tongtsen Yülsung back to Tibet and to escort Wencheng. When they arrived in Tibet, Songtsen Gampo was said to be so pleased that he bowed to Li Daozong, using ceremony appropriate for a son-in-law toward a father-in-law. He built a palace for Wencheng and changed into Chinese clothing before he met her. It was said that at that time, the Tibetan people had a custom that Princess Wencheng hated—that people would paint their faces red—and that he prohibited the custom for her sake.
