Zhao Mengfu
Remnants of the Song imperial family continued to live in the Yuan dynasty like Emperor Gong of Song, Zhao Mengfu, and Zhao Yong. Zhao Mengfu spent his time painting at the Yuan court and was personally interviewed by Kublai Khan. The "Vietnamese Annals" recorded that remnants of the Song imperial family arrived in Thăng Long, the capital of the Đại Việt, in the winter of 1276 aboard thirty ships and eventually settled in the Nhai-Tuân district and opened a market selling medicine and silk.
