According to the "Tang Yun" (Tang Rhymes), this is a common variant of the character "nü". The "Pian Hai" (Sea of Characters) states that "nü" can also be written as "nü", with a character structure composed of "blood" and "chuang", where "chuang" signifies the meaning of wound. The "Zheng Zi Tong" (General Dictionary) considers "nü" and "nü" to be two separate characters, which is incorrect.
