Phượng is also used as a masculine name in Vietnamese. A form of this name used for both genders is Phụng (I think). However, Phượng is more common for females. So, I think that the "Gender" of this name should be changed from "Feminine" to "Feminine & Masculine".Sources: https://www.names.org/n/phuong/about https://forebears.io/forenames/phuong
