三催四请

三 = 一 + 二 : Mnemonic symbol: a 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 ants. Moreover, he's balancing on a Cartesian coordinate system (三). Unfortunately, only three (三) ants stop to watch the performance.

催 = 亻 + 崔 : Kitty Cat (cu) still wants to get the sparrow, so she urges (催) Rosa Luxemburg (亻) to climb the high snow-covered, precipitous mountain (崔) in front of the Eiffel Tower (ei1).

四 = 儿 + 囗 : Mnemonic symbol: a four-leaved clover. Socrates (s) is working out in the bathroom of the space station (Ø4). He's lifting four (四) wooden boxes (囗), and wonders why they are so heavy. He doesn't know that inside one of the four boxes, the monkey king (儿) is hiding and secretly laughing at him - until the monkey king comes out and surprises Socrates with a four-leaved clover (四).

请 = 讠 + 青 : The Queen of Hearts set up a fountain of youth right in the middle of the engine. She invites everyone to take a sip and even set up an advertising column to motivate the visitors to come and try it.
