The last remaining survivors of the Lý Dynasty had fled to Korea following Trần Thủ Độ's total massacre of the Lý family. One of famous Lý survivors was Lý Long Tường, who later helped to defeat the Mongols and halted total Mongol occupation of Korea for many years, even though Korea was eventually forced to become a Mongol vassal. For these efforts, he was revered as one of the most important heroes in the Mongol wars and became a significant part of history forming the historical and mutual bond between Korea and Vietnam that exists for eight centuries and still remains since.
