Is there any historical allusion to the origin of prickly heat?

In ancient times, scorpions were called coolers. More than 2000 years ago, Qu Yuan, a famous patriotic poet in China, wrote The Songs of Chu. Evocation, there is a sentence that says "there is something wrong with the honey bait." What are the honey bait, enamel \ \ \ \ enamel? Lin Hong's textual research in Song Dynasty: "A glutinous rice line is a person who lacks water", "A glutinous rice line is a cold food, so there is nothing suspicious". Liu Yuxi, a poet in the Tang Dynasty, once wrote a poem entitled "Cold Weapons": "The delicate jade hand has been ground several times, and the green oil has been fried into light yellow and deep. It doesn't matter if you sleep in the spring at night, but it's hard for a beauty to hug gold. "

But some people say that this is not written by Liu Yuxi, but an advertisement poem written by Su Dongpo for an old woman who sells "cold food". No matter who the original author is, this poem vividly describes the "cold weapon" of fried food, which is sweeping and enough to make people drool. So what exactly is a cold tool? In the Compendium of Materia Medica written by Li Shizhen in the Ming Dynasty, it was clearly stated that "cold dishes can be eaten as soon as they are opened, and glutinous flour and flour are used to knead them into a circle with little salt ... The entrance is as crisp as Ling Xue". It can be seen that prickly heat and twist, an ancient unusual food, can be compared with it.

There is also a legend about why the ancients ate "cold utensils". It turns out that the day before in ancient Tomb-Sweeping Day was a folk cold food festival, and it would take three days to catch fire. Jin Lu (Sui Yu) wrote "Nakano Ji", which recorded that "mesons pushed the fire and ate cold food for 150 days after the Japanese winter". It is said that meson tui lived in exile with his son Zhong Er for 19 years. When he was starving in Zhong Er, he once gave his share to the monarch, which can be described as loyalty. However, after Zhong Er returned to power as Jin Wengong, he forgot meson push when discussing merits and demerits. So meson pushed his mother to Mianshan to live in seclusion. One day, Jin Wengong suddenly remembered meson push and personally took people to Mianshan to look for it. When he disappeared, he ordered the release of Yamakaji, trying to drive the mother and son out. Unexpectedly, meson refused to see Jin Wengong, and both mother and son were burned to death. Therefore, Jin Wengong was very sad and angry with the fire. Three days before his death, he ordered meson to push the national fire ban, so there was the Cold Food Festival. What shall we eat without fireworks for three days? That's the refrigerator, fried, which can be preserved and kept crisp and skinless. Of course, it is the most ideal food.
