can be like Wu Taibo." He thus took his favorite concubine Lady Gao and his extensive book collection, got into a ship, and sailed to Later Tang. In 930, he arrived at Later Tang's Deng Prefecture (登州, in modern Yantai, Shandong). (Yelü Bei's wife Imperial Queen Xiao and his oldest son Yelü Ruan did not follow him to Later Tang, and Imperial Queen Xiao would subsequently continue to rule the Dongdan state until her death in 940, while Yelü Ruan would eventually succeed Emperor Taizong after his death (as Emperor Shizong).) As Later Tang subject During Emperor Mingzong's reign In 931, Emperor Mingzong made Yelü Bei the military governor (Jiedushi) of a newly created Huaihua Circuit (懷化, headquartered in modern Baoding, Hebei), and gave him a new name of Dongdan Muhua.
