蘑菇蘑菇它不开花石头石头它不结果
[mó gū mó gū tā bù kāi huā shí tóu shí tóu tā bù jié guŏ]
This nickname is composed of nonsensical sentences that rhyme in a childish manner, meaning 'The mushroom doesn't bloom; the stone doesn't bear fruit'. It reflects a whimsical or fanciful character who appreciates playfulness.
