Who can tell me the background and origin of oatmeal?

Naked oats Athena Chu yóu miàn Interpretation Naked oats are millet. The growth period is short, and the fruit is easy to break away from the shell after maturity. It can be eaten after being ground into powder, which is called oat powder, naked oat powder and oil wheat powder. The fruit of this plant is also called naked oats. Flour made from naked oats. After careful preparation, it became food. The nutritional content of oat flour is more than 7 times that of other flours, which can be compared with refined flour. Yomi contains calcium, phosphorus, iron, riboflavin and other nutrients and pharmaceutical ingredients needed by human body, which can treat and prevent diseases such as diabetes, coronary heart disease, arteriosclerosis and hypertension. At the same time, oat flour contains a special substance-linoleic acid, which has obvious effect on human metabolism. In addition, oat noodle is a good health food, which is helpful to lose weight and beauty. It's just that oatmeal is not easy to digest (it's best not to eat it for dinner), so eat less. Oil noodles are a special food in Zhangjiakou, Hebei Province. Zhangjiakou folk jingle "Three Treasures of Zhangjiakou" contains: "Three Treasures of Zhangjiakou, Yam, Oil Cotton, Large Leather Coat." The main producing areas are Zhangbei County of Zhangjiakou and Wuchuan County of Inner Mongolia. Watching the TV series Journey to the West is too empty and boring, and it doesn't really reflect the grand theme of Journey to the West. It is as light as a feather flying in the air and has no weight at all. Walking to the west is an important part of northwest culture. Although I haven't studied it in detail, going to the west has always been a topic that northwest people talk about after dinner. The TV series "Walking to the West" only presents people with the traditional cultural phenomenon of "walking to the west" around a few people in Qixian County, Shanxi Province, which is obviously not rational enough. Although there are many scenes in the play that can highlight local customs, the essence of Shanxi culture has not been outlined. For example, in addition to oil noodle restaurants, such as Daoxiao Noodles and shadow play, this thing may be more orthodox and authoritative in Shaanxi. After reading "Going West", I think of "Qiao Family Courtyard", which is totally two kinds of feelings. In fact, the "Qiao Family Courtyard" can better reflect the profound connotation of Shanxi culture, and the famous Shanxi merchants have pushed all the humanistic spirits of Shanxi culture to the extreme. Just as a joke, it is far from convincing to build a "family courtyard" by doing odd jobs in the West. "(Yin Qian's TV series The Truth of Failure)
