one's way
🍳 勝 (win) + 手 (hand): a hand that wins its own way = doing as you please
The kitchen sense is the room where you handle things your own way. The same word covers 'one's way' and selfishness, since both mean acting without yielding to others.
手 — pictograph of a hand with five fingers
手 is a pictograph showing an open hand with fingers and a wrist. Early bronze and oracle bone forms clearly depict five splayed fingers, which simplified over time into the modern shape. It keeps its original meaning of 'hand' and also serves as a radical in many characters related to hand actions.
