The raw rice noodles in Nanning are delicious. I want to ask about his origin and what allusions he has.

Raw pressed rice noodles originated from Pumiao Town, Yongning District, Nanning (formerly Yongning County). Pumiao Town is a small ancient town on the Yongjiang River. It is said that the ancestors of this town created the delicious raw pressed rice noodles hundreds of years ago. The ninth day of September and the fifteenth day of September in the lunar calendar are big festivals in nearby Zhuang villages. In addition to preparing big fish and meat, every household cooks raw pressed rice. Put it in a fire room and bury it in plant ash for two or three days. Let the rice slurry ferment slightly, which is a bit sour. On the day of receiving visitors, set up a cauldron to boil hot water, squeeze the powder, and cook a cauldron of bone soup at the other end. Chop the semi-fat pork, add the chopped Nostoc flagelliforme, stir fry together, squeeze the rice noodles, put them in a bowl, pour a spoonful of minced meat on the Nostoc flagelliforme, sprinkle with chopped green onion and add some points.
