There is also a small story about the origin of the hot dry paste: in the 1930s, there was a grocer named Lee Bao on Hanguchi Longti Street, who lived off the sale of cold powder and soup noodles. On one occasion, the noodles were not sold, and he feared that they would be spoiled, so that the remaining ones would be boiled and dried and laid on the board. I accidentally bumped the kettle on the case and poured it on the noodles. The bag had to put the noodles in oil. The next morning, Li Bao put the oiled noodles in the boiling water and made them boil into the bowl, and then added to it the spices used to sell cold powder, which tasted good. Some asked him what face he was selling, and he said it was “hot noodle”. Since then, he has been selling such faces, not only to compete with each other, but also to teach him a lot of lessons。
