Although this is unofficial history's secret, even Zhao Yi, a storyteller, commented that "this rumor is nonsense". However, it can be seen from the wide spread of this article in unofficial history that many people are very afraid of "eating wool when sick". When it comes to specific hair products, many people have the same idea: mushrooms, fish, shrimps and crabs, bamboo shoots, pumpkins, pig's head meat, roosters ... In fact, few medical experts and scholars have made clear definitions and special comments on them in professional works of traditional Chinese medicine. The word "Mao" was first found in the local classic "Puji Fang" in the Ming Dynasty, which recorded scrofula, aphtha, hair ban and so on. Hair includes mutton, peaches, plums, sparrow meat and blood. Qin Bowei, a modern famous doctor, pointed out in "Dietary Problems of Patients with Traditional Chinese Medicine" that all leeks, mushrooms and cauliflower will cause dry mouth, red eyes, swollen gums and constipation. There is the possibility of fever, commonly known as "hair". Generally speaking, the "Mao" in the mouth of elders is more like the dietary taboos such as "taboo" and "two kinds of food can't be eaten together" in China traditional food culture, which has developed into special dietary guidance for patients.
Patients with diarrhea, constipation, hemorrhoids and gastrointestinal surgery should not eat indigestible foods such as glutinous rice and fried peppers; Patients with skin allergies, it is best to bid farewell to high-protein or allergic foods such as seafood, shrimps, crabs and mangoes for the time being; Gout patients also need to reduce the intake of high purine food. For your convenience, I have made these classifications for hair products. You can have a look: now, we don't define anything, but discuss it from a literal and pure scientific point of view. Canadian paleontologists found five dinosaur eggs in a nest full of sand. Through the study of these nests and eggs, Canadian scientists say that dinosaurs first built nests similar to bird's nests and laid eggs similar to birds' eggs, and then dinosaurs evolved into birds (chickens are also a kind of birds). In other words, eggs exist before chickens. Chickens evolved from these egg-laying carnivorous dinosaurs. Why did dinosaurs lay such eggs like bird eggs? The germ cells of dinosaurs are closely related to their reproduction. The DNA that determines the genetic material in cells will be mutated by physical factors such as radiation, temperature, chemical carcinogen benzene, coal tar and virus.
If these factors lead to genetic material DNA variation in germ cells, it will have a great impact on future generations. For example, the DNA mutation of dinosaur germ cells caused the next generation of dinosaurs to lay eggs similar to bird eggs. After hatching, the creatures in the egg may have the physiological function of laying eggs, and then evolved into today's chickens after several stages. Some friends may have questions. If we define the dinosaurs that laid eggs as birds (chickens are also a kind of birds), then these theories should not be overthrown. In this regard, Tadpole Jun wants to say that biology has a certain classification method. Modern biological classification originated from Linnaeus's system, which classifies species according to their common physiological characteristics. According to the above viewpoint, the first dinosaur that laid dinosaur eggs similar to bird eggs has no difference in physiological characteristics with other dinosaurs, but its eggs have some variation, which is similar to bird eggs and should be classified as dinosaurs according to biological classification. So eggs first, then chickens.
