Wang Su was exiled to Yangmok-gun, Gyeongsan-bu (now Yangmok-myeon, Chilgok-gun, North Gyeongsang Province) in 1099 (4th years reign of King Sukjong) without detailed case or charges,[11] but it was recorded that the king personally gave books related Confucianism and Buddhism to his brother who was going to the exile place.[12]
In 1112 (7th years reign of King Yejong), Wang Su committed a crime again and moved to Geoje-hyeon while his only son, Wang Myeon exiled to Jillye-hyeon (now Geumsan-gun, South Chungcheong Province) at the same time. On his way to Geoje-hyeon, Wang Su died at Hyeonpung-hyeon (now Hyeonpung-eup, Dalseong-gun, Daegu-si)[13] and Yejong then stopped the inquiry for three days upon hearing about his uncle's death. A year later, Wang Myeon was pardoned and able to return to Gaegyeong, also received back his position as Sagong .[14]
