狂瞽（上渠王反字書云病也韓子曰心不能審得失之地則謂之狂說文從犬王聲也下公戶反孔注尚書云無目曰瞽舜父有目不能分別好惡故時人謂之瞽也）。

Kuanggu 狂瞽 (The first character has the fanqie phonetic spelling [k- + -uáng > k-] qú wáng 反. The Zishu says: "An illness." Master Han says: "When the mind is incapable of carefully assessing gains and losses, it is called kuang 狂." The Shuowen jiezi states it takes the dog radical with 王 as the phonetic. The second character has the fanqie phonetic spelling [g- + -ǔ > g-] gōng hù 反. Kong's commentary on the Shangshu says: "One without eyes is called gu 瞽. Shun's father had eyes but could not distinguish good from bad, hence the people of the time called him Gu").
