Heung Su

In 660 king Uija of Baekje sought to prepare for war against the Silla–Tang alliance seeking advice from Yeon Sin (義直) and the Dalsol, Sang Yeong (常永) but could not come to a decision.

"[1] The princes did not believe him and said, "we must pass the Baekgang River and it will be like killing the chicken in the cage or catching the fish caught in the net."

King Uija decided to go with the second plan and Baekje's army was destroyed and the capital fell to the enemy.

[2] Samchungsa shrine in Buyeo County, South Chungcheong Province was built in 1957 in memory of three loyal officials of Baekje in the mid-7th century - Seong Chung, Heung Su and Gye Baek.

Heung Su desperately advised the king to keep the strategic military point of Tanhyeon, when the unified forces of Silla and China's Tang dynasty invaded Baekje.
