Mnemonic symbol: "son" (儿) sounds similar to "Sun" like in "Sun Wu Kong", so it's gonna be represented by the monkey king. Albert Einstein (Ø-) and Sun Wu Kong (儿) are fighting in the space station's kitchen (-Ø2). Their weapons: Albert Einstein has a shovel (乚), and Sun Wu Kong has a banana (丿).

凵

Mnemonic symbol: a vicious (凶) demon mask. Xu Xian (xu) tried out an electric demon mask (凶) in front of the engine ((e)ng1), but now he can't take it off anymore. He already tried to pull the cable out of the receptacle (凵), but it didn't work. Maybe he has more luck using pliers (乂) to pull at the mask.
