In November 935, when King Gyeongsun expressed his intention to surrendered Silla to Goryeo, Taejo sent an envoy in return this request.[9] Taejo also wanted to married with Silla's royal member and Gyeongsun said:
"Our Uncle, Kim Eok-ryeom has a daughter that both of her virtue and appearance are beautiful."
"우리 백부(伯父), 김억렴(金億廉)에게 딸이 있어 덕(德)과 용모가 쌍미(雙美)한지라 이가 아니면 내정(內政)을 구비(具備)할 수 없을 것."[10]
After this, Gyeongsun sent his older first cousin, Lady Kim to Goryeo and become the 5th wife of Taejo.[11]
