雌雄

雌 = 此 + 隹 : The King of Chu (c) is wooing a female (雌) sparrow (隹) just inside the space station's entrance (Ø2). He knows that women like shoes, so he brought a pair of big and expensive boots (此), unfortunately much too large for the small female (雌) sparrow (隹).

雄 = 𠂇 + 厶 + 隹 : Xu Xian (xu) is on a trip and thinks that he is the greatest one (雄) in the engine's kitchen ((e)ng2). He thinks so until a small sparrow (隹) flies by and cuts off his fake nose (厶) using a pair of scissors (𠂇).
