In the ancient times, DengShao from HongNong(弘農) embarked on an herbal expedition to HuaShan(華山) on the first day of the eighth month. To his astonishment, he encountered a celestial child holding a five-colored pouch, collecting dewdrops from cypress leaves. These dewdrops resembled pearls and filled the entire pouch. Intrigued, Shào inquired, “What is the purpose of this?” The celestial child replied, “Master Chì Sōng utilizes these to enhance vision.” With these words, the celestial child vanished without a trace.
In the present day, people fashion “Clear Vision Pouches” on the first day of the eighth month, unknowingly continuing the legacy of this mystical encounter.
Original story in 《齊諧記》弘農鄧紹，嘗八月旦入華山采藥。見一童子，執五彩囊承柏葉上露，皆如珠，滿囊。紹問曰：「用此何為？」答曰：「赤松先生取以明目。」言終，便失所在。今世人八月旦作眼明袋，此遺象也。
