三令五申

三 = 一 + 二 : Mnemonic symbol: Cartesian coordinate system with three (三) axes. Socrates (s-) is performing in front of the anthill (-an1). He created an electrical flute by attaching a large capacitor (二) to the flute (一), so that he can get the attention of all the people. Moreover, he's balancing on a Cartesian coordinate system (三). Unfortunately, only three (三) people stop to watch the performance.

令 = 今 + ㇏ : As a mnemonic symbol, I'm going to use a 令牌, which was a tablet to identify someone as an official sent by the emperor to convey the emperor's orders.

令 = 今 + ㇏ : Li Qingzhao has been sent by the emperor to collect rent from the English, but they are nowhere to be found. Finally, Li Qingzhao arrived at the engine's bathroom, ready to show her 令牌, raise the finger and show to the date of payday on the calendar—if there were anyone in the engine's bathroom.

五 = 王 + 丨 : A pentagram.

五 = 王 + 丨 : Martin Luther King helps Willy Walrus to construct a pentagram out of dinosaur bones inside the space station.

申 = 丨 + 曰 : Sherlock Holmes uses a microphone and a dinosaur bone as pointer to explain the history of the encampment to the audience standing in front of it. He likes to present himself as an expert, but he's a faker: All his explanations come from his textbook.
