I think we know where the Cho daughters got their bad temper from:
Police said Monday they began a preliminary investigation into the wife of the Korean Air Line Co. chief over alleged physical and verbal violence.
Lee Myung-hee, wife of Chairman Cho Yang-ho and director of the Ilwoo Foundation, is suspected of hitting workers who were part of a construction crew hired to remodel her Seoul residence in 2013.
She allegedly told them to kneel down and slapped them in the face and kicked them in the shins.
She is also suspected of verbally insulting an employee at a Incheon-based hotel affiliated with Hanjin Group, which includes Korean Air, and later having the worker quit for not recognizing her. [Korea Times]
