Who knows what this is called?

Ai Ai (Ai Gao Ai Zan) is a traditional snack of Han nationality, which is usually eaten in Tomb-Sweeping Day. Wormwood can be regarded as a common ingredient on Hakka table. Every spring, clumps of wormwood grow by the water in the field, and the green leaves spiral up, which is as lovely as a pagoda. At this time, the Hakka mother will take the children to pick them, go home and steam glutinous rice, then mix them with mugwort leaves and mash them into rice paste, wrap some peanuts or sesame seeds in the middle and steam them in a pot, which becomes a very famous mugwort in Hakka cuisine.
