There is a theory that this and the King of Chu have a link, it is said that in the past, the first Ling Wang good waist, the geographical location of Chu, often regarded as barbarians, so the waist will be called "Chu waist" or "barbarians waist".
But some people believe that this argument is not credible, because even in the Spring and Autumn and Warring States period, the southern part of Chu is not part of the range of barbarians, on the contrary, Chu's colorful culture, compared with the civilization of the Central Plains is not inferior.
Another theory says that the true origin of the barbarian waist may have something to do with the Tang poet Bai Juyi, or rather with two of his courtesans.
Ancient scholars had the habit of keeping a female kabuki, Bai Juyi had two special favorites kabuki: Ji people Fan Su, good song; kabuki people small barbarians, good dance. Bai Juyi also wrote a poem for them praised: "Cherry Fan Su mouth, willow small savage waist." This can be seen in the cherry mouth and willow waist of the source.
