"Tiangong Kaiwu" is a scientific and technological masterpiece written by Song Yingxing in the Ming Dynasty. The book has an exquisite explanation of many things. However, the book does not directly mention "crab". Therefore, the following is an explanation of the main uses of crabs in classical Chinese from the perspective of the ancients:
Crab, born on the banks of rivers and seas, has a wide range of uses.
One of them can be used as a delicacy. Crab meat is tender and delicious, making it the best food for diet. Every golden autumn, when chrysanthemum crab is fat, people often use it as a delicacy. Or steamed or boiled, accompanied by ginger vinegar, when you eat it, the fragrance is overflowing. Although the cooking of crabs is not detailed in "Zhou Li · Tianguan Tsuzai No. 1", there are traces of eating crabs at that time. By the time of the Wei and Jin Dynasties, the trend of eating crabs gradually flourished, and the literati and scholars were much better. The meat of crab chops tightens and flaps teeth; the crab roe and crab paste are plump and mellow, making people unforgettable. It is really a gift from heaven, and you can enjoy the appetite.
Second, it has medicinal effects. According to ancient medical books, the taste of crabs is salty and cold, and it has the functions of clearing away heat, dissipating blood stasis and reducing swelling. After its shell is processed, it can be used as medicine, and it has a certain curative effect on some sores, swelling and blood stasis. Although the ancients paid attention to the compatibility and processing of medicine, the medicinal value of crabs was also recognized and used by the ancients, and it was one of the aids for the treatment of diseases.
Third, it has a unique meaning in culture. The rampant state of crabs often arouses the associations and feelings of literati and writers. Its hard shell and rampant posture symbolize perseverance and unruly, which is often reflected in poetry and paintings. As Pirixiu's poem goes: "It was famous before swimming in the sea, and it was born from flesh with bones. Mo Dao was fearless of thunder and lightning, and the sea dragon king was also rampant." Crabs are used to express their own aspirations and feelings. And the eight feet of crabs are also given the meaning of "hair", which means auspiciousness and wealth. In folk culture, they carry many good expectations.

"Tiangong Kaiwu" is a scientific and technological masterpiece written by Song Yingxing in the Ming Dynasty. Although it does not specifically explain the physical properties of the "Horned Beast", its physical properties can be speculated based on ancient records and related legends.
The Horned Beast is relatively large, and it is rumored that its body is strong, or comparable to large livestock such as cattle and horses, and its limbs are thick and powerful, so it can support its huge body and move freely. Its body is thick and fur, and it may have good warmth and protection functions, which can resist external damage and severe weather.
The most significant feature of the Horned Beast is the horn on the top of the head. This horn is hard and sharp, just like steel. When encountering danger or used in combat, it can become a powerful weapon, with powerful piercing and attack abilities. And this horn may contain some unique texture, or have a certain toughness, not simply hard and easy to fold.
The Horned Beast's eyes are bright and energetic, and its eyesight is keen. It can see clearly in dark environments or at long distances, making it easy to detect surrounding movements, avoid danger or find food. Its ears must also be extremely sensitive, able to accurately capture subtle sounds and sense potential threats in time.
In terms of action, although the Horned Beast is huge, it is not clumsy. It is agile, runs fast, and has good flexibility. It can quickly travel through complex terrain such as mountains, forests, and grasslands. Its call is loud and can be transmitted far, which can be used for communication between groups, and can also play a role in deterring enemies when necessary. These physical properties constitute the unique biological characteristics of the Horned Beast, which makes it unique in legend and imagination.

Borax, its chemical properties are specific. The main component of borax is sodium tetraborate, and its formula is $Na_2B_4O_7\ cdot10H_2O $.
Looking at its physical properties, borax is often colorless and translucent crystal, or white powder, brittle and glassy on the surface, and easily soluble in water.
As for its chemical properties, borax aqueous solution is alkaline. Due to the hydrolysis of borax in water, borate ions combine with hydrogen ions in the water, resulting in an increase in the concentration of hydroxide ions, so the solution is alkaline. This alkaline property plays a key role in many chemical processes and industrial applications.
Borax has strong coordination ability. Boron atoms are in the borax structure, and its outer electronic structure allows borax to form coordination compounds with many metal ions. This property makes it useful as a flux in the metallurgical industry. At high temperatures, borax can combine with oxides on the metal surface to form fusible borates, which help remove impurities on the metal surface and reduce the melting point of the metal, making the metallurgical process smoother.
Borax also has buffering properties. Within a certain range, it can adjust the pH of the solution, so that the pH value of the solution remains relatively stable. This buffering property is very important in chemical analysis and some chemical reactions that require precise control of pH. For example, in some biochemical experiments, borax buffer solutions are often used to maintain a specific pH environment to ensure the activity and stability of biomolecules.
Borax will gradually lose its crystal water when heated. First, part of the crystal water is separated, and then continuous heating can cause borax to completely lose water and then decompose. This change in thermal stability is of great significance in the fields of ceramics, glass and other industries, in adjusting the melting point and melting characteristics of materials.

One of them is the method of harmony.
One of them is the method of harmony. It is necessary to maintain good health, its back is solid, its color is bright, and its limbs are powerful. It is clear and clear. It is not advisable to be sick or sick, and it is not effective.
The second is the matching of raw materials. Often supplemented by herbs, people, wolfberry, and other herbs. Herbs, which calm the mind and benefit the blood; People, large yuan, and solid; The wolfberry, nourishing the liver, clear eyes; Herbs, promoting blood circulation, and relieving pain. Compatibility according to a certain ratio, seeking efficacy and effectiveness.
Third, the method of harmony. For the first time, soak it in clean water and make it clear to the stomach. Then, take the raw material and soak it in a large amount of water, and torture it until it is finished. When it is cold, put it in the cold, so that it will be natural. If it doesn't work, you can use utensils to help, and take it a small amount of times. During the long period, you need to pay attention to the problem of the cold. If it is normal, stop it immediately.
Fourth, the way of the cold. It is appropriate to place it in a place where it is clear and common, to avoid exposure to the hot sun, and to use suitable food, such as small, black, snail, etc., to help it recover and increase its effectiveness. Only with such careful care can you get the true effect of the cold.

The Tibetan antelope is a treasure of life on the plateau. Its storage and transportation must be handled with great care, and many matters must not be ignored.
First, the Tibetan antelope is a state-level protected animal, and it is illegal to hunt, kill, eat, and trade it. When storing and transporting it, you must first ensure that the behavior complies with the law and must never get involved in illegal activities. This is the top priority, which is related to the balance between species survival and ecology. If you violate this article, you will be severely punished by the law and cause great harm to the ecology.
Second, if it needs to be stored and transported for legitimate reasons such as scientific research, a suitable environment should be created. Tibetan antelopes have lived in cold places for a long time and have unique habits. When storing, the temperature and humidity must be precisely controlled to simulate its original environment to prevent its body from spoiling or quality damage. When transporting, it is also necessary to ensure that the environment is stable and free from unfavorable factors such as bumps, high temperature, and humidity.
Third, the transportation process must be fast. The longer the delay, the greater the impact on Tibetan antelope samples or products. Choose an efficient transportation method and take protective measures to avoid damage caused by vibration and collision. At the same time, environmental parameters should be closely monitored during transportation to ensure that they are always suitable.
Fourth, whether it is storage or transportation, detailed records must be kept. Including source, quantity, processing method, transportation route and time, etc., for inspection and traceability. This can ensure the transparency of the whole process, prevent illegal circulation, and also facilitate the orderly development of scientific research and other work.
Furthermore, those engaged in related work should have professional quality and a high sense of responsibility. Familiar with the characteristics of Tibetan antelope and storage and transportation specifications, rigorous and meticulous operation, so as not to make big mistakes due to negligence.
