Revolving Doors of Vengeance (Traditional Chinese: 酒店風雲) is a 30-episode TVB series which was released in 2005.

The story befalls the family of Wong Yuk Ting (Lau Dan) who runs a five-star hotel chain and tells of how repaying a favour turns into seeking vengeance in a twisting story of honour and revenge.

Then Yuk Ting suddenly dies mysteriously and the business is strangely handed to a man named Ko Fung (Joe Ma) to head.

He develops a romance with Bik Kei (Kenix Kwok), whom he meets in the hotel and becomes embroiled in a tangled power struggle with the family, including Kit's uncle Wing Fat (John Chiang), where deceit and plots unfold around every twist and turn.

Ko Fung saved the business for another purpose and because of this, him and Kai Kit were always at odds.
