Chen and women regard smallness as yin, and men regard tallness as yang. For example, girls' names use the characters Wei, Miao, You, Bei, Lei and Qiao; boys' names use the characters Feng, Lan, Lei, Hong, Yuan and Hong. Si, for women, virtuousness is the yin, and for men, erudition is the yang. For example, girls' names use the words Hui, Qiao, Xian, Shu, Xiu, Ya, Xiang, etc.; boys' names use the words Bo, Cai, Qi, Hua, Zhang, Xian, Guan, Kui, Han, Ru, etc. In the afternoon, women use insects and birds as yin, and men use beasts as yang.
