井底之蛙

rú guǒ tā men zòng róng zì jǐ de ān quán gǎn tā men jiù huì biàn chéng jǐng dǐ zhī wā

如果他们纵容自己的安全感，他们就会变成井底之蛙。

If they indulge in this sense of security, they will become a frog in a well.

jǐng dǐ zhī wā shì kàn bù dào wài miàn de shì jiè de kāi kuò hé měi hǎo de

井底之蛙是看不到外面的世界的开阔和美好的。

A frog in a well cannot see the wide outside.
