我是钻石会发光散光会爆炸
[wŏ shì zuàn shí huì fā guāng sàn guāng huì bào zhà]
This translates as 'I am a diamond, I glow and scatter light, but if you do not take care of me properly, I may also explode', symbolizing one with talents or strong points who needs due attention but also has potential temper or explosive characteristics.
