Xao is of Vietnamese origin, meaning "peace" and "harmony". It's pronounced as "show", similar to the English word "show". This unisex name is often used for both boys and girls in Vietnam but has gained international recognition recently due to its unique sound and positive meaning. The name Xao is typically spelled without accents, although it can also appear as Xiào or Xiâo with tonal marks in Vietnamese.
"The name Xao experienced a small peak in popularity with eight births recorded in 1991, following which it maintained a steady average of six births per year until 1993, leading to a total of twenty-seven children bearing this unique name over these four years."
