Deaf and blind (聾瞽: the second character has the sound g- [姑] + -ǔ [午] fanqie. Zheng's commentary on the Rites of Zhou says: 'Lacking eyes is called gǔ; when the eyes do not open, sprawling as if with blind skin. Having pupils but unable to see is called méng; having eyes but lacking pupils is called sǒu; they are also called máng.' The Shuowen says: 'Formed from the eye radical (目) with gǔ (瞽) as phonetic').
