Wulianghe, its main user, is also food.
Wulianghe is the ancient Jiagu, with different types and multiple functions. The first priority is to feed it, which is the foundation of people's livelihood. In ancient times, based on farmers and mulberries, the grain produced by Wulianghe filled the belly of the people and nourished the bodies of all the people. The people take food as their heaven, and the reality of Wulianghe is pounded for cooking, or for rice, or for porridge. It is steaming and fragrant. It is the staple food of daily life. It is full and nourishing.
Furthermore, it is also important in the ritual of sacrifice. The ancient sacrifice was to respect the sky and Fazu to show piety. The refined grain of Wulianghe, choose the best one and serve it in a sacrificial vessel, and offer it to the ancestors before the gods as a sacrifice. Because Wulianghe was bred by heaven and earth, he obtained the essence of nature and sacrificed it, hoping that the ancestors of the gods would enjoy it, and blessing the world, protecting the peace of the family and the country, and the abundance of the grain.
And Wulianghe also has extraordinary performance in the brewing industry. It can make fine wine, which can be fermented and distilled to obtain nectar and jade liquor. The fine wine is used in banquets and drinks, and the guests are rewarded to add joy; in ceremonial occasions, it is also an indispensable thing, showing solemnity and respect. Its mellow taste, soft or strong, all comes from the unique character of Wulianghe, bringing a wonderful experience to the drinker.
The leftover material of the five sorghum can be fed to livestock. The livestock can be fed to be fat, and then provide people with meat, eggs, etc., forming an ecological cycle and increasing the benefits of people's livelihood. Therefore, the use of the five sorghum is related to diet, sacrifice, brewing, and animal husbandry. It is the key to the lives of the ancients. It is a treasure bestowed by God and relies on people's livelihood.

If there are five edges, the materiality of the object can be studied. The husband has five edges, with a bottom surface and a five-shape, and the corners of the bottom surface are intersected with each other.
Let's talk about what shape it is first. If there is a five-shape shape on the bottom surface, plus the five-shape triangle on the bottom surface, a total of six faces are obtained. If it is low, there are five surfaces on the bottom surface, and there are five surfaces in the bottom surface, so it is combined with ten. And it is low, and the bottom surface is five, plus one, a total of six.
As far as its qualitative, in terms of three-edge and four-edge, the bottom surface of the five-edge is large, but there are many surfaces, and the center of gravity is relatively flat. Its qualitative is slightly less. If it is placed on the plane, it is easy to collapse due to a little external force.
Re-talk about its center of gravity. The center of gravity of the pentagonal veil is located on the vane leading from the vane to the center of the bottom surface, and close to the center of the bottom surface. If you want to make it balanced, you need to adjust it according to the characteristics of its center of gravity.
And its light reflection is equal. The light is projected on it, because of the different oblique angles of each surface, and the reflection direction of the light is different. If it is shot with parallel light, it will be reflected on all sides, the light will be scattered, and the reflection of the plane will be large.
Furthermore, its capacity will be reduced. If you know the height of the bottom pentagonal surface and the height of the pentagonal surface, according to the formula tolerance\ (V =\ frac {1} {3} Sh\) (\ (S\) bottom surface,\ (h\) height), you can find its tolerance. This is the materiality of the pentagonal surface in terms of tolerance measurement. In short, the materiality of the pentagonal surface has its own characteristics in terms of shape, qualitative, center of gravity, light reflection, tolerance, etc., which can be further studied.

The five river puffer is also a species in the water. Its chemical properties are unique and interesting, and I will describe them in detail today.
The body of the five river puffer contains special chemical substances. In its organs, there are many toxins, which are called river puffer toxins, which are strong and poisonous. The river puffer toxin is a neurotoxin with a delicate and complicated chemical structure. It can inhibit the transmission of nerve impulses and has a special role in the sodium ion channel of the nerve cell membrane. When the toxin is combined with the sodium ion channel, it is difficult for the sodium ions to pass through the channel smoothly, causing the transmission of nerve signals to be blocked. This poison is very powerful, and a small amount can kill people. It is very cautious for people to cook river puffer.
However, the five river puffer is not all evil. Chemical substances that may have medicinal potential in their bodies. In today's world, medical research is unremitting, and some scholars hope to find a cure from pufferfish toxins. Although this toxin is poisonous, if it can be used properly, it may be used as an analgesic medicine. Due to the effect of pufferfish toxin on nerve conduction, it can precisely act on the pain nerve, and is expected to be developed as a new type of analgesic drug to relieve the pain of patients.
In addition, the epidermis and mucus of pufferfish also contain chemicals. Such substances may have antibacterial and anti-parasitic effects, which can help pufferfish resist foreign invaders in water. The chemical mechanism is that these substances can destroy the cell structure of bacteria or parasites, or interfere with their metabolic processes, making it difficult for them to survive and multiply. From this point of view, the chemical properties of the five river puffer, although there are dangerous toxins, but also hidden potential for human use, is a complex gift of nature, waiting for the world to explore in depth, in order to understand and make good use of it.

The five-beam crown is a crown ornament made in ancient times. The production process is quite complicated, and there are many precautions in it, which cannot be ignored.
The first heavy material selection. The quality of the material is related to the quality of the crown. When choosing the best wood, it is better to have a fine texture and a tough texture. The wood needs to be carefully dried to remove its moisture to prevent future deformation. Or use flexible bamboo strips. When weaving, you can make the crown light and strong at will.
It is essential to make the frame. The size must be accurate, according to the size of the head circumference, and there must be no mistakes. The structure of the frame needs to be stable and well-proportioned, and there must be no skewed state. If the frame is not correct, the crown on the head is also difficult to correct. The junction of the frame should be joined by mortise and tenon, or firmly wound with silk thread to ensure that it is tight and seamless, and can withstand the test of time.
Weaving the crown surface is a clever place. If woven with bamboo strips, the strips should be uniform in width and narrow, and neatly arranged. Various weaving methods, or cross-crossing, or back-pattern coiling, all need to be skilled in techniques to make the crown surface texture beautiful and properly spaced. If the fabric is used as the surface, the color and texture should be carefully selected. When cutting, according to the shape of the frame, the edges should be neat and smooth, and there should be no stagnation.
Decorative embellishment should not be ignored. Decorate with beautiful jade, pearl and other decorations in front of or on both sides of the crown. The embellishment should be moderate. If it is too much, it will be extravagant, and if it is too little, it will lose its splendor. Decorative objects should be firmly inlaid, and there should be no fear of loosening, so as to show the delicate and solemn crown.
Color and paint to add color to the crown. When the color is suitable for clothing and occasions, it should be a calm color for solemn occasions; when celebrating festivals, bright colors can be selected. The paint needs to be applied evenly and the thickness is moderate. It not only enhances the luster of the crown, but also protects its material and is durable.
In the production of the five-beam crown, every link needs to be dedicated and attentive. Follow the ancient method in order to become a good product. Those who wear it show their authority and style.

The influence of the five-year-old on the environment and people's health has been known in ancient times. "Tiangong Wuzi" says: "All kinds of beans, millet, millet, millet, hemp, and beans must be sown. However, the land is suitable, and the sky is suitable. It has different effects on people's health."
In terms of the five-year-old environment, its planting characteristics have a great impact. For example, rice, which likes water, is mostly planted in paddy fields in the south. Its production requires a lot of water irrigation, but its soil and water conservation efforts are also effective, and the root system fixates the soil, which can reduce soil erosion. And the millet, drought tolerance, suitable for the dry land in the north, can effectively use the dry soil source, less irrigation depends on the balance, the distribution of different nutrients in the right place, so that the land source can be fully utilized, and the variety of fertility.
As far as human health is concerned, each of the five is beneficial. The "Emperor" says: "Five", this is also true. Rice, sweet in taste, good for the gods, good for the gods, good for the middle, often eaten can be spleen and stomach, fill the muscles., especially small, can calm the mind, in addition to quenching thirst, the north eats more food, because of its nature, can be cold evil. Bean, such as soybeans, rich in protein, can strengthen the spleen and spleen, water and eliminate, often eaten can be healthy. Millet of millet, which warms the spleen and stomach, stops diarrhea, and has an effect on the spleen and stomach. Hemp seeds, which are not often eaten today, were also one of the five in ancient times, with the effect of laxative.
Of course, the five are in the environment, according to their own characteristics; for people, with their different effects, they are the things of heaven and earth, which cannot be ignored.
