In "Tiangong Kaiwu", the main use of the borer moth is recorded. The book records that the borer has children and bears them. The larvae of the borer moth are often parasitized by parasitic wasps such as the borer.
From an agricultural point of view, many types of larvae of the borer moth are crop pests. For example, the larvae of the rice borer will bite the leaves of rice, and the newly hatched larvae will gnaw on the leafy flesh at the edge of the leaves, causing the leaves to appear white short-line-like streaks; when it is slightly larger, the leaves will be bitten into blanks. In severe cases, the leaves can be eaten up, leaving only the veins, which greatly affects the photosynthesis of rice, hinders the growth of plants, and reduces the yield of rice. In order to protect crops, farmers often need
However, from an ecosystem perspective, the borer moth, although a pest, is also an important link in the ecological chain. As a prey, it provides food resources for many natural enemies and maintains ecological balance. Its adult insects can pollinate some plants and promote plant reproduction. In addition, the borer moth itself can also be used as a research object to help people explore many biological characteristics such as insect physiology, ecology, and behavior, which is of great significance to the development of entomology.

"Tiangong Kaiwu" is a scientific and technological masterpiece written by Song Yingxing in the Ming Dynasty. Although the book does not specifically describe the specific thing of the "sly monkey", according to the relevant historical knowledge and the ancient understanding of animals, the physical properties of the sly monkey can be speculated as follows:
- ** Physical characteristics **: The sly monkey is usually small and dexterous, with slender and flexible limbs, which allows it to quickly climb and jump between mountains and forests, and travel freely between branches. Its body length is about one foot or more, and its tail length is similar to its body length. It maintains body balance with its long tail and moves in complex canopy environments.
- ** Hair texture **: The hair is soft and fine, which can resist wind and cold and adapt to the changeable climate of mountain forests. The coat color may be brown, gray-brown, etc., which blends with the mountain and forest environment and plays a protective role, helping it hide its body, avoid natural enemies or approach prey.
- ** Skeletal Muscles **: The bones are light and tough, which not only reduces weight for easy movement, but also has enough strength to support the body. The muscles are developed and powerful, especially the limb muscles, which give it strong climbing, jumping and grasping abilities. It can hang on tree branches for a long time and can quickly capture prey.
- ** Sensory Characteristics **: The eyes are large and bright, and the vision is keen. It can clearly see objects in the dark mountain and forest, and detect food and danger. The ears are also sensitive, and can detect subtle sounds and sense changes in the surrounding environment. The sense of smell is also more developed, helping it track prey, identify companions or mark territory.
- ** Physical Habits **: Sly monkeys like to inhabit tall trees and feed on fruits, young leaves, insects, etc. Because of their sly intelligence, strong adaptability and learning ability, they can adjust their foraging and activity strategies according to environmental changes. They are more active during the day, foraging, playing, and socializing among branches; at night, they seek safety in tree holes or dense foliage to rest.

The snake of the viper has a strong and poisonous nature, and its chemical properties are mostly related to poisons. The venom of the snake contains a genus of proteins and polypeptides, which are the key components of its harm.
Proteins are of various types and have their own characteristics. Or they can break the membrane of human cells and cause cells to disintegrate; or they can disturb the order of blood coagulation and cause blood disorder. Peptides are also very effective, can stimulate the end of human nerves and cause severe pain; or they can disturb the contraction of human muscles and make limbs numb.
And in the venom, enzymes are often contained. Protein hydrolase, which can eat human tissue and cause skin and flesh to fester; phospholipase, which can damage the membrane of cells, release the content of cells, and cause inflammation and swelling.
In addition, the chemical properties of its venom are also affected by the environment. If the temperature is high, the activity will increase, and the poison will be rapid and intense; if the temperature is low, the activity will decrease, and the poison will be slow and weak. In case of acid and alkali agents, or disturbed by chemical substances, its poison can also change.
Although the venom of the viper is evil, it is also useful in the way of medicine. Good refining, rational processing, and taking the beneficial ingredients of its poison can make analgesic and anticoagulant drugs, which are helpful for treating patients and saving people.

Although the method of making furs for raising foxes is not explicitly mentioned in "Tiangong Kaiwu", according to the records of the ancients on fur production and related skills, the following inferences can be made.
When making furs, the first priority is to choose the skin. Fox fur is divided into upper, medium, and lower according to the part and quality. The upper-quality fur is mostly taken from the back of the fox's spine. The fur is plush and thick, the needle hair is straight, and the color is smooth; the abdominal fur is slightly inferior, and the short hair is thin. When making furs, choose the best materials to get good products.
After choosing the leather, it needs to go through the soaking process. Soak the fox skin in warm water and alkaline substances such as grass and wood ash. This is to remove grease, stains and impurities, so that the skin is clean and helps in subsequent tanning. When soaking, turn the skin often to ensure that all parts are soaked in place, and grasp the soaking time. If it is too long, it will damage the toughness of the skin.
After soaking, it will be tanned. In ancient tanning, alum, saltpeter and other substances are commonly used. Alum, saltpeter and water are mixed into a solution in proportion, put in the fox skin, and cook slowly over low heat or soak for a long time. During this process, alum, saltpeter, etc. penetrate into the skin and combine with the protein in the skin to make the skin soft, durable and resistant to corrosion. During tanning, check the condition of the leather sheet from time to time to refer to pinching the skin. If there are white dents on the skin surface and it disappears quickly, it indicates that the tanning is moderate.
After tanning is completed, organize it again. Use a knife or scraper to remove the remaining meat scraps, fat and other objects from the skin to make the skin surface flat. Then unfold the leather sheet and hang it in a ventilated place to dry. Do not expose it to the sun to prevent the skin from becoming hard and cracking. When the leather sheet is semi-dry, rub it with your hands or tools to promote softness.
After the leather sheet is dry and soft, cut and splice it according to the design. Cut the fox skin into the desired shape and sew it with silk thread. When sewing, pay attention to the direction of the hair and the color matching, so that the fur coat is beautiful. After splicing, the edges are modified and arranged, and the neckline, cuffs, etc. are sewn on, and a fox fur jacket is made.

It is necessary to clear the busy place and avoid the dark place where the tide is, so that it is easy to cause diseases and skin diseases. And it is appropriate to keep the empty space open so that the body can live freely without suppression. Furthermore, the living environment of the hidden place is often beat to sterilize the body and ensure its well-being.

It is also important to keep the body clean. First, it is necessary to combine the tools. If it is a short journey, it can be used to buy soft things to make the body comfortable. If it is a long journey, it is also a good strategy to use it, such as transportation, fire, etc., but it is important to pay attention to the quality and keep it warm and cold. Second, it is necessary to check the body during the journey. It is necessary to check the spirit, food, excretion, if necessary, and management. Third, it should also be considered to avoid the hot summer heat and cold winter days, and set off in a pleasant time.
In this way, it is important to hide or hide, and take care of the heart and make comprehensive arrangements to ensure a safe journey and avoid trouble.
