Ai Ci is a traditional Han snack, usually eaten during the Qingming Festival. Mugwort is a common ingredient on the Hakka dining table. Every spring, clumps of mugwort will grow beside the fields and water, with green leaves spiraling up, looking very cute like a pagoda. At this time, the hostess will take the children to pick them, steam the glutinous rice at home, mix it with mugwort leaves, and grind it into rice paste, wrap some peanut or sesame fillings in the middle, and form small green dumplings into the pot. Steamed in it, it becomes a very famous Hakka delicacy.
