Office Yeo In Cheon Ha (오피스 여인천하) is a Korean party game developed by Danbi and released for Korean arcades in 2001. Similar in vein to the likes of Bishi Bashi Special or Salary Man Champ by Konami, the game revolves around three newbie female office workers who take on 31 wacky minigames to determine who is the best office worker.

Ku_Zheng_Kai completes the game with the left and right office worker in record time.

Note for viewers: There is a slight graphical glitch in the in-level scoreboard/timer where the shadow is magenta instead of a darker shade of the representative player, but this is very minor.
