To break your legs

Hearing the insulting remark toward his best friend, Yu Chen could not stay quiet.

"Yujin, are you proud of the fact that you are General Lee's son? Then, you need to look at yourself in the mirror and find out what's your value here. Why did General Lee choose to demand the rank one position for Lee Xianwu instead of you? That's the place you hold in this family. General Lee will choose Xianwu no matter what," he asserted and advised Yujin not to make futile attempts to win over his father.

"I take my leave," Yu Chen said and left Yujin's sight.

Yujin felt humiliated and also got upset once more that their father chose to appeal for the highest-ranked position in the kingdom for Lee Xianwu instead of him. Xianwu never once worked, never once studied hard, and failed in everything, yet their father chose him above his second or third son.
