懂得太多遭雷劈知道太少遭淋雨
[dŏng dé tài duō zāo léi pī zhī dào tài shăo zāo lín yŭ]
The name translates to 'Knowing too much gets struck by lightning; knowing too little gets caught in the rain.' This metaphor means balancing knowledge is important because both overconfidence and ignorance can cause trouble in life.
