Xiao xian cao is a kind of tea bag. In order to design a sense of ceremony, mystery, interest and international quality, the designer selected the tea drinking of palace ladies' sleeves covering their mouths in the Tang Dynasty as the main visual expression to let more people know and love tea in a more interesting way. On the back, the easy to understand "tea" is used to convey the category and enhance the sense of quality. The small tea bag uses the aluminum foil bag with independent small package, which is convenient for consumers to carry and drink.
