Extended information:

During the Spring and Autumn Period and the Warring States Period, the "cold utensils" eaten during the Cold Food Festival were called prickly heat. At that time, in order to commemorate Jie Jietui, a famous minister of Jin State in the Spring and Autumn Period, the Cold Food Festival (one or two days before Tomb-Sweeping Day) was forbidden for three days, so people fried some ring-shaped pasta in advance as a fast food during the Cold Food Festival, which was called "cold utensils".

After the founding of New China, the Cold Food Festival gradually merged with Tomb-Sweeping Day in one day, and the custom of forbidding fire and cold food in the Cold Food Festival has long been lost, but the prickly heat related to this festival is deeply loved by the world, and it is still a seasonal food suitable for all ages today.
