Yelü Bei
Shulü Ping was born in 879. Her great-great-grandfather Shulü Nuosi (述律糯思) was said to be of Huigu extraction. Her father was named Shulü Pogu (述律婆姑), who also had the name of Yuewan (月碗), served under the Khitan Yaonian (遙輦) clan. Her mother was said to be a daughter of "King Yundejia" (勻德恝王) — apparently the grandfather of her eventual husband Yelü Abaoji, Yelü Yundeshi (耶律勻德實) — which would make her and Yelü Abaoji cousins. Eventually, she married Yelü Abaoji as his wife, but it is not known when that occurred. She bore Yelü Abaoji three sons — Yelü Bei, Yelü Deguang, and Yelü Lihu.
