The source of idioms as blind as a bat

According to "Zhuangzi Foreign Things": "The eye is not without beads, because the heart is not watching." Eyes don't grow on beads, so you can't see the value of beads, but your mind is not on it, so you can't understand the value of beads. Later, there are two idioms called "as blind as a pearl" and "as blind as a pearl", which describe that people only see the appearance of things and lack the ability to really understand the inside of things.

According to "Historical Records": "In the ninth year of Yijing Emperor, the barbarians first cut Burma (now Burma) ... decorated their ears and inserted pearls to make them beautiful. Qi Huangong said, "You can send a messenger to get it." When he arrived, the savage said, "This is not for the messenger. No private pearl can enter your body. Poor knowledge can't be obtained, but on the contrary, I met Gong Jing again and told what I heard. Gong Jing said, "The messenger took it. The barbarian said,' Your Majesty is deeply rebellious, and the pearls and jade in the palace can be taken at will without being a thief. Do you want to take pearls because of me?

Therefore, I can walk with big countries and protect them with trust. What you did today is the way to save the day. You can't do it. Hearing this, Gong Jing was ashamed and evil, and gave it to Huan Yi. This means ignorant behavior, losing the overall situation, ignoring the overall situation and being blind and arrogant. So it later evolved into the idiom "as blind as a bat", which is used to express that people can see an object with their eyes, but they can't realize its value, and they can't understand the truth, so let it go.
