"Hanh" is one of the rarest names in Vietnamese, you'd be lucky if you knew someone whose name is Hanh. It is one of those names which has grown out of fashion since the beginning of the 21st century for its blandness, some of the others include: naming children after numbers (Muoi, Tam,
Bay), and naming children after farm animals (Ga, Lon, Cau). "Hanh" derives from the Vietnamese word (derived from Chinese) meaning
joy. Looking back, having such a rare name is a goldmine for bullies ( people call you
peanut, chestnut, etc), but as an optimist, being a "Hanh" is such a unique experience,
cuz you're the only one in school with the name, hence, none of my
teachers have actually forgotten my name...
