不识之无 is a Chinese idiom (chengyu) meaning “illiterate”. Unable to recognize even the simplest characters; unlettered; completely uneducated. Literally, “not know 'zhi' and 'wu'”.
During the Tang Dynasty, the great poet Bai Juyi was exceptionally intelligent from a young age.
According to the 'New Book of Tang,' he was able to recognize the characters 'zhi' and 'wu' by the time he was seven months old, a fact his wet nurse confirmed without fail through numerous tests.
His letter to Yuan Zhen further corroborates this: 'When I was six or seven months old, my wet nurse held me near a screen with writings. Someone pointed to the characters 'wu' and 'zhi' for me. Although I could not speak then, my mind had already silently recognized them.'
