^Choe was an eunuch during the reign of the Princess's nephew, King Chungnyeol who was said to had several ferocious dogs. Someday, one of them bit and eventually killed the Princess's female servant. Due to this, she asked Choe to not keep a ferocious dog again, but he said:
"How long will Princess prevent me from owning a dog?" ("궁주께서는 앞으로 살 날이 얼마나 된다고 내가 개를 기르는 것을 못 하게 하십니까?")
Which she then shed tears and mourned. Also, Choe was believed to commit many other crimes and then interrogated by her grandnephew, King Chungseon who was the crown prince at that time.
