劳务交换

劳 = 艹 + 冖 + 力 : Mnemonic symbol: a very hardworking laborer from the 劳动人民.

A laborer worked very hard to outfit the aorta's kitchen with artificial lawn and an electrically movable sunshade made from a cooking top. As he finishes he is overjoyed to play with the sunshade, having it move up and down, to and fro in crazy ways. As Lancelot enters, Lancelot pushes the off button and gives the laborer an upset look, asking without using words what nonsense he's doing.

务 = 力 + 夂 : Willy Walrus practices a performance in the space station's bathroom. To honor the CCP, he dances wearing high heels. The grande finale is a banner that is unrolled upon hitting a power button, which reads "为人民服务".

交 = 亠 + 父 : Linus Pauling, a famous scientist with a beret. Father Time commands Linus Pauling to hand over his beret to him in front of the aorta, but Joan of Arc comes to his rescue.

换 = 奂 + 扌 : Helga Horse (hu) received two new toy claws (扌) and tests them in the anthill's bathroom (an4). To test whether they are the same, she repeatedly exchanges (换) them and weighs them in her hands. She then makes both tips of the claws touch and quietly whispers "excellent" (奂).
