Yelü Xiuge (耶律休哥) (died 998) was an important Khitan general and politician in ancient China's Liao Dynasty. He commanded a disciplined army and fought the Song forces for several decades, taking care to not harm any innocent individual. The "History of Liao" records that adults in Song Dynasty would yell "Here comes "Yuyue" (于越; Yelü Xiuge's title)!" to stop children from crying.
