[4] However, a rebellion began in 190 when the king tried to stop Lady U's relatives (including Eobiryu and Jwagaryeo) from abusing their power.
After King Gogukcheon's death, Queen U met with his brother Prince Balgi to discuss the throne's successor.
[6] According to the historical source Samguk sagi, during the ensuing conflict, Yeonu was injured by a knife, and U loosened her skirt scrap and used the fabric to cover the wound.
As a test of his generosity and patience, she once had him cut the mane of his horse, and on another occasion she ordered a servant to spill soup on his clothes.
Rather than retaliate against U, he granted her clan political influence by appointing them to the highest position of state minister, and he continued to honour her as the queen dowager (왕태후; 王太后).
When King Dongcheon read this, he planted seven layers of pine trees around Gogukcheon's tomb to hide and cover it.
