In the state of Chu, there lived a scholar so destitute that he and his wife could barely afford food or clothing. One day, the scholar sighed to his wife, "I am as poor as can be, yet I have a talent for writing. I shall go to the capital and seek my fortune." His wife replied, "But you have no connections or money—how will you even get there?" The scholar smiled and said, "I have heard that the King of Chu values talent above all. I will write him a letter and present myself at court." With nothing but his wits and a few scrolls, he set off. Upon arriving at the palace, he knelt before the king and declared, "Your Majesty, I may be poor, but I possess the wisdom of a thousand scholars. Grant me an audience, and I shall prove my worth." The king, intrigued, ordered him to be fed and clothed, and soon the scholar rose from rags to riches, all because he dared to speak up. This story reminds us that even in the direst poverty, a bold heart and a sharp mind can open doors.
One day, while reading, a scholar happened upon a passage: "If you obtain the leaf a mantis uses to shield itself when catching a cicada, you can conceal your form and become invisible, unseen by others."
The scholar believed it to be true and waited daily beneath the tree for his chance. At last, he spotted a mantis lurking behind a leaf, eyeing a cicada with predatory intent. Overjoyed, he snatched the leaf, but it fell and mingled with the others on the ground. Unable to tell them apart, he gathered several bushels of fallen leaves and carried them home.
Once home, the scholar picked up leaf after leaf, covering his eyes with each one, and asked his wife, "Can you see me?" His wife, thinking he was being silly, kept replying, "Yes, of course I can see you." He repeated this all day until she grew utterly annoyed and finally humored him with a lie: "No, I can't see you."
The scholar was overjoyed—after a day of desperate searching, this was exactly what he had been waiting for. He grabbed the leaf and dashed into the street.
Once on the street, he saw a fruit vendor and decided to steal a fruit. So, he picked up the leaf, held it over his eye, and reached out to grab one. The vendor, furious at such a brazen theft in broad daylight, grabbed him on the spot, tied him up with rope, and hauled him straight to the county magistrate.
The county magistrate interrogated the scholar, asking, "Why did you steal someone else's belongings?"
The scholar, his face flushed crimson, stammered out the entire story from beginning to end and begged the county magistrate for forgiveness.
The county magistrate burst into laughter, immediately released the scholar, and imposed no punishment whatsoever.
Later, people used the idiom "A Leaf Before the Eye" to describe being blinded by trivial matters, unable to see the bigger picture.
