Mnemonic symbol from 加油 (jia1 you2): cheerleaders' pom poms.
Joan of Arc (ji) works on her cheer-leading skills in front of the ashram (a1). For the grande finale of her performance she prepared special effects: at the very end of her performance she hits a power button (力) on the floor with her foot, which starts mandarins (口) shooting from her pom poms (加).
