Tingzhi (李庭芝) and Miao Zaicheng (苗再成), planned to hijack a transport to carry them all but failed. The group arrived in Dadu in May, and then proceeded to Shangdu, where Kublai Khan received them in the Hall of Great Peace (大安殿). Kublai conferred the noble title "Duke of Ying" (瀛國公) on Zhao Xian and a princess title on Zhao Xian's ethnic Mongol wife, Lady Borjigin. Kublai Khan further ordered that Zhao Xian and Lady Borjigin be given a residence in Dadu and receive preferential treatment. In 1298, Zhao Xian was given permission to move his residence to Shangdu. Between 1314 and 1320, the Yuan ruler Emperor Renzong received the Goryeo ruler Chungseon at his court. Chungseon asked to see visit Zhao Xian's residence and composed a song about him. Relocation to Tibet Kublai Khan wanted to preserve some vestiges of the Song imperial clan and in October 1288 issued an edict ordering Zhao Xian to relocate to Tibet.

Later on, Zhao Xian took over as the head monk at the monastery, translating Buddhist texts between the Chinese and Tibetan languages under the name "Sman rce Lha btsun" (, Chinese: 蠻子合尊 manzihézūn), which means "royalty of Mangi" (southern barbarian) in Tibetan language. Death According to Sakya's monastic succession records, in 1323, the 52-year-old Zhao Xian received an imperial edict ordering him to commit suicide at Hexi (河西; present-day Zhangye, Gansu Province. Many Ming Historians believed that this was because Zhao Xian's poetry displeased the Yuan ruler, Emperor Yingzong. Other Ming historians believe that Emperor Yingzong feared a coup led by Zhao Xian. The renowned Sinologist Ann Paludan has written, "[His] unexplained suicide in 1323 led to
