Guangyun, Jiyun, and Leipian record the pronunciation as bian (falling tone); Yunhui and Zhengyun record the pronunciation as bian (falling tone). This is the original form of the character for a ceremonial cap. According to the Shuowen, it refers to a ceremonial cap. The original form was written as the character appearing as the roof radical over the character for child. The Zhou dynasty called it by a name pronounced as bian (rising tone), the Yin dynasty called it by a name pronounced as xu (rising tone), and the Xia dynasty called it by a name pronounced as shou (level tone). It is derived from the appearance of a face and is a pictographic character. The ancient seal script form is written with an additional element. The modern standard form is abbreviated as the character for ceremonial cap. The Zhengzitong notes that the Zihui incorrectly writes it as a different form, and it also notes that the character appearing under the see radical is an incorrect variant.
