Aiwowo It is a traditional snack in Beijing, and it is also a spring and autumn food. Later, it was served all year round. Aiwowo was originally a "royal Aiwowo", and later it was introduced to the people from the court in the Ming Dynasty. Every year around the Lunar New Year, this variety is served in snack bars in Beijing and sold until late summer and early autumn. Aiwowo has a long history, and Liu Ruoyu, an internal supervisor during the Wanli period of the Ming Dynasty, said in "Deliberating on the Records":

Taking glutinous rice with sesame seeds as a cold cake and pills as a nest, that is, the ancient' not falling' is also true.

Aiwowo, as an old Beijing halal snack, once wrote a poem:

White sticky rice is put into the steamer, and the assorted stuffing and flour are rubbed. Muddy as glutinous rice balls, it's called Aiwowo.

Its characteristics are white as frost, delicate and flexible texture, and loose and sweet stuffing.
