The Choujiu is a type of Chinese fermented alcoholic beverage(a liquor or brew containing alcohol as the active agent) brewed from glutinous(something that is glutinous is very sticky) rice. It is very thick and has a milky white color, which is sometimes compared to jade.
Choujiu is an ancient variety of Chinese wine, and is possibly the original Chinese wine. It can be traced back to the Tang Dynasty, wher it was praised by the poet Li Bai. In ancient times, choujiu was referred to as yujiang.
In this modern day, the city of Xi'an is known particularly for its choujiu(稠酒chóujiǔ).
