Yin Collection, Upper Volume Radical: Roof (mián) Entry: Qiong Kangxi Stroke Count: 6 Page 282, Entry 01 In the Correcting Character Guide (Zhengzitong), it is stated to be identical to the character for "vault" (qióng), representing a corrupted and simplified version of that character. The Dictionary of Characters (Zihui) notes that it is pronounced qióng. The term refers to the shape of the sky. The characters for "vault" and this term were incorrectly split into two separate entries. In classical historical records and canons, it is typically written as the standard character for "vault" (qióng), and is not found written as this character.
