Aici is a springtime delicacy exclusive to the Hakka people of Shaoguan. Also known as Aiban or Qingtuan, Aici has traditionally been an offering for ancestral worship, symbolizing reunion and serving as a means to honor and remember ancestors. Over time, it has evolved into a traditional Qingming Festival delicacy. Aici is made from mugwort and glutinous rice. Each spring, when mugwort is tender, locals gather fresh mugwort leaves and mix them with steamed japonica or glutinous rice, pounding the mixture into rice paste. They then fill the paste with a sweet filling made of peanuts and sesame, shape them into small green dumplings, and steam them. This process creates the famous delicacy known as Aici.

　　When eating Aici, Hakka people enjoy brewing a pot of black tea and complementing it with snacks like fresh bamboo shoots and hawthorn, enhancing the delightful experience.

　　In 2021, the technique for making Renhua Aici was listed in the eighth batch of intangible cultural heritage of Shaoguan City.
