In "Tiangong Kaiwu", the thirteen harriers are in the shape of a hawk, and their main uses are three.
One is field hunting. The ancient nobles often enjoyed field hunting, which both practiced martial arts and showed their strength. The thirteen harriers play a unique function on this occasion. Its body is shaped like a hawk, and when hunting in the field, it can use ingenious mechanisms, or such as a hawk to rush and pounce, startle the prey, so that the prey flees to the preset encirclement area, helping the hunter capture; or make a sound similar to the sound of a hawk, disturbing the audio and visual of the prey, making it panic and fall into the hunter's trap.
The second is used for military reconnaissance. During the war, intelligence is crucial. The Thirteen Harriers can rely on their delicate construction, or fly quietly at low altitudes, approach the enemy camp, spy on the enemy's troop deployment and camp layout; or hang high, take advantage of the wind to stabilize their body, like "tailwind" and "clairvoyant", observe the enemy's movements, and provide key intelligence for their own military decision-making. Its concealment and mobility have significant advantages in the field of military reconnaissance.
The third is to transmit information. Ancient communication is inconvenient. After special training, the Thirteen Harriers can carry simple letters or tokens, fly according to the set route, and travel to and from specific locations. When communicating urgent military situations or important affairs, they can break through terrain obstacles and quickly deliver information, becoming one of the effective means of information transmission, making up for the lack of speed and flexibility in human transmission of information.

The physical properties of the thirteen chickens are quite unique. Its feathers are gorgeous in color, like a glow shining in the sky, dazzling, and when touched, it feels as soft as brocade, slippery without leaving its hands. Its body is solid and well-proportioned, with exquisite bone structure and tight muscles, showing a kind of agile beauty.
Its beak is hard and sharp, like a cast of fine steel, it can easily peck through its shell and forage for all kinds of insects and grains. Its eyes are bright and sharp, like shining stars, and can perceive subtle changes in the surroundings. Whether it is the concealment of natural enemies or the traces of food, it is difficult to escape its eyes.
Its feet are strong and powerful, and its claws are sharp like hooks. It can walk like a fly in rugged places, and when fighting, it can be used as a powerful weapon to kick and tear, with extraordinary power. Its body temperature is often maintained in a warm state, not afraid of cold and heat, not afraid of the scorching sun in hot summer, and can resist the cold wind in cold winter.
Its chirping sound is crisp and loud, echoing in the mountains and forests. The sound can be heard for miles, or the dawn is announced, or the warning of the same kind can be clearly heard. This chicken's feathers are well insulated, which can keep the heat in the body from dissipating, and can dissipate heat in the heat. Its bones are light and strong, making it easy to fly, jump, and adapt to changing environments. These are the unique physical properties of the thirteen chickens.

"Tiangong Kaiwu" reports that the thirteen-spiced dogwood has relatively stable chemical properties.
Dogwood has a warm nature, a refreshing and bitter taste. From a chemical point of view, it contains a variety of chemical components, such as volatile oils, alkaloids, etc. The structure of these components is relatively stable, and under normal conditions, it is not easy to undergo significant chemical changes due to external minor factors.
In terms of storage, it can be stored for a long time at room temperature, dry and well-ventilated places without easy deterioration, which highlights the stable side of its chemical properties. In the process of processing and application, after conventional heating, grinding and other treatments, its main active ingredients can still be well retained and maintained in a relatively stable state. Adding dogwood to cooking can give full play to its unique aroma and seasoning effects, and when it interacts with other ingredients, it will not react sharply due to general cooking conditions, resulting in significant changes in properties.
It is based on the observation that the chemical properties of dogwood in the thirteen spices are quite stable, so it can maintain its own characteristics and play a corresponding role in many application scenarios.

"Tiangong Kaiwu" says: "The method of making the thirteen pigs is as follows. First choose a good hog, the coat is moist and the one with a strong figure is better. Place the hog in a spacious and clean place, and wait for its mind and body to fit.
When slaughtering a hog, first bind its four hooves with ropes, so that it cannot be moved, but also pay attention not to be too tight, so as not to hurt its body. Break its throat with a sharp knife, and it will die of blood. Immediately scald its hair with hot water. The water temperature should be suitable. If it is too cold, the hair will be difficult to remove, and if it is too hot, the skin will be easily damaged. After ironing for a while, shave its hair lightly with iron shaving and other materials,
After the hair is cleaned, place the hog on the case, and cut it along the midline of the abdomen with a sharp blade, taking care not to hurt its internal organs. Take its internal organs first, clean them one by one, and discard the stomach and intestines. If the liver, lungs, heart, etc. can be kept, wash them for later use.
Then, divide the meat according to the part. Take its front and rear legs first, which is the essence of the meat. The meat is fresh and tender, and can be made into a variety of delicacies. Then take its belly meat, fat and thin, suitable for stuffing and stewing. The meat on the back has a clear texture, and can be sliced and fried. Pig head and pig trotters also have their own wonders, either braised or stewed, and the taste is good.
After it is divided, it is marinated with salt, pepper and other seasonings, which can enhance its flavor and is conducive to preservation. In this way, the preparation of the thirteen pigs is completed, and the meat made, whether cooked or mixed, is delicious. "

When storing and transporting the thirteen chickens, you must pay attention to many matters. First, choose a good storage place. The storage place should be dry, cool and well ventilated. If it is in a humid place, the thirteen chickens are easily eroded by moisture, resulting in damage to their quality or mildew. A cool environment can slow down their deterioration and maintain their characteristics. The ventilation is smooth, which can remove odor and moisture, and prevent the growth of bacteria.
Second, choose the packaging method carefully. The material of the packaging should have the ability to protect. It should be made of strong and moisture-proof materials to prevent the thirteen chickens from being damaged during handling, and it can also withstand external moisture and impurities. And the packaging must be well sealed to ensure that its aroma does not dissipate and the taste is as pure as ever.
Third, control the temperature of transportation. During transportation, temperature is very important. Extreme heat can easily cause the thirteen chickens to rot, and severe cold may damage their texture. Therefore, the temperature should be controlled at an appropriate value according to its characteristics. If it is transported by cold chain, its quality will remain unchanged.
Fourth, handle it with care. When handling the thirteen chickens, do not treat them rudely. The texture of the thirteen chickens is delicate, and they can be broken or deformed by throwing and squeezing them with force, which will damage their appearance and internal quality.
Fifth, prevent fouling and odor. During transportation and storage, keep the thirteen chickens away from pollution sources, such as chemicals and sewage. And should not coexist with odorous things, because it is easy to absorb the taste, causing the original taste to be mixed and losing its original fragrance.
During the whole process of storage and transportation of the thirteen chickens, care should be taken and attention should be paid to all details in order to ensure its high quality and serve everyone.
