According to legend, in the fifth year of the Northern Song Dynasty (1053), the court sent Di Qing, an envoy of the Tang Dynasty, to lead the farmers to Pennsylvania (now Binyang County), and the farmers were stuck in Kunlun Pass, which is 0/9 km west of Binyang County. On the Lantern Festival night, Di Qing arranged lanterns in the camp, held a banquet to confuse each other, but secretly sent two thousand green riders to sneak up on Kunlun Pass from behind, and then suddenly attacked from front to back. Kochi was caught off guard and fled. Escaped to Dali, Yunnan, and Di Qing won a great victory. During Di Qing's stay in Binyang, most of his subordinates were northerners. They don't like rice and ask for noodles. Pennsylvania is rich in rice and lacks noodles, so it is difficult to meet the requirements. However, no matter how hard it is, it can't beat the savvy Pennsylvania people. People soak rice, grind and steam it into rice flour, and send it to the camp with ingredients such as salt water slices. After eating, the soldiers were full of praise for the rice noodles. It's early spring in the south, and the temperature rises suddenly, which is sultry as summer. Soldiers in the north are not acclimatized, and they have diarrhea, chills and no food. Pennsylvania people carefully remoulded rice noodles, steamed them into thin slices, and served them with rice vinegar, pickled cucumbers, coriander and other seasonings for soldiers to eat. Unexpectedly, this kind of acid powder is really amazing. After eating it, the soldiers felt their appetite was wide open and refreshed, and diarrhea and boils were actually cured. Soldiers all call this kind of powder with the functions of refreshing, relieving summer heat, quenching thirst, appetizing, eliminating dampness and clearing heat acid powder. Since then, Pennsylvania sour powder has become a unique local snack, handed down from generation to generation, enduring.
Binyang people love to eat sour powder, and the diners in the noodle restaurant are like clouds. Coupled with an endless stream of foreign diners, hotels, restaurants, small restaurants and food stalls in Binyang County are full of sour powder supply. Among the acid powder stalls all over the street, the one with the longest history and the best taste should be the first to promote the acid powder of Luwei Nanjie. Yan Jia, Guanjia, Zou Jia and Laobian have been handed down from generation to generation with a long history. Nanjie acid powder is well-selected, handmade and unique.
There is also a legend about the delicious Binyang acid powder. Legend has it that there is a filial daughter-in-law who is very kind to her grandmother. Her grandmother is ill, so she can't eat hard food and has no appetite. Seeing that grandma was getting thinner and thinner, the daughter-in-law was anxious, so she changed a way to cook good food for grandma. But in the hot summer, my wife can't eat greasy food, so my daughter-in-law grinds rice into powder, cooks it with water, makes it soft and tender, and adds sweet and sour seasoning to make my wife's appetite big. After the careful service of the daughter-in-law, her illness soon recovered, and the sour powder was passed down with her filial piety, which was deeply loved by people.
