Turtle armor is a commonly used Chinese herbal medicine. Its main uses are quite extensive, and it has many important functions in the field of traditional medicine.
From the perspective of nourishing yin and latent yang, although "Tiangong Kaiwu" does not elaborate on the use of turtle armor in this regard, in the theory of traditional Chinese medicine, turtle armor has the power of nourishing yin. When the human body's yin fluid is deficient, the virtual heat is endogenous, and symptoms such as hot flashes in the afternoon, night sweats, bone steaming and hard work occur, turtle armor is often used. It can nourish the human body's yin fluid, calm down virtual heat, and bring yin and yang back into balance. For example, among many prescriptions for nourishing yin and reducing fire, turtle armor is a key medicinal material, helping the human body restore the state of sufficient yin fluid.
Soft and strong loose knots are also important uses of turtle armor Turtle armor can play a role in coping with conditions such as agglomeration and accumulation in the body. For diseases such as liver and spleen enlargement, abdominal masses, etc., traditional Chinese medicine often borrows the power of soft and firm turtle armor to dissipate and accumulate. This effect is based on traditional Chinese medicine's cognition of the operation of qi and blood and the function of the viscera. It is believed that agglomeration is mostly caused by stagnation of qi and blood, and agglomeration of phlegm and dampness. Turtle armor can gradually soften and dissipate hard agglomeration.
In addition, turtle armor is often used to benefit the kidneys and bones. For children with fontanelle incompatibility caused by congenital deficiency or acquired atrophies, as well as symptoms such as sore waist and knee, weak muscles and bones caused by liver and kidney deficiency, turtle armor can benefit the kidneys and fill in sperm, promote normal bone growth and development This is in line with the theory that the kidney dominates the bone in traditional Chinese medicine, and provides sufficient nourishment for bone growth by nourishing the kidney yin.

The method of casting swords is related to survival and operation, and there are many taboos in the process, which must not be ignored.
When casting swords and storing materials, the first material selection is excellent. The material of the sword, such as fine iron, cold steel, etc., must be pure in texture. This is the foundation of the sword. If the material is poor, the quality of the sword will be difficult to be strong and unusable. The material selection needs to look for good ore, and the iron needs to be pure in color and quality, without impurities and defects, in order to be the foundation of the sword.
Furthermore, the method of storage should not be ignored. The material should be placed in a dry and ventilated place to avoid moisture and rust. If stored in a dark and humid place, iron is easy to rust and erode its quality, and it is difficult to make a good tool when casting. And the materials should be classified and stored, and different materials should be placed in their own place, so that they can be used and not confused.
As for the process of casting swords, the control of the heat is the key. The size and duration of the fire are all related to the quality of the sword. If the fire is small, the iron is difficult to melt and difficult to shape; if the fire is large, the iron is easy to overmelt and damage its toughness. When the first melting, the fire should be large and fierce, so that the iron can melt quickly; when forming, the fire needs to be gradually tempered to refine its properties. Swordsmiths should use experience to observe the change of the heat and make timely adjustments.
The hammering of the sword is also exquisite. The hammering force needs to be uniform and the rhythm is orderly. Heavy blows can make the sword body dense, and light strikes can flatten its surface. The strike part should also be precise. The force on the sword body needs to be balanced everywhere, so that the sword body is straight and has no skewing.
The method of quenching is to give the sword a combination of rigidity and softness. The quenching liquid, or water or oil, has its own uses. Water quenches the sword and oil quenches the sword. When to enter water or oil, it is all up to the swordsmith's eye and judgment. If the quenching is not proper, the sword may be brittle and easy to fold, or soft and weak.
The way of forging swords requires careful treatment in the selection of materials, storage, heat, hammering, hardening, etc., in order to forge a good sword for combat or other purposes. This is an essential rule that cannot be forgotten when forging swords.

The physical and chemical properties of turtle armor and human (1:1) are as follows:
turtle armor has a salty taste and a slightly cold nature. It contains animal glue, keratin, a variety of amino acids and trace elements. In terms of physical properties, turtle armor has a hard texture, an oval shape, a raised carapace, and a textured surface. After processing, the texture is crispy, which is conducive to crushing and frying out active ingredients.
From a chemical point of view, it contains animal glue, which is macromolecular collagen. It can be partially hydrolyzed when heated in water to generate a variety of amino acids, which have certain viscosity. Amino acids are rich in components, such as glycine, alanine, etc. These amino acids are the basic units that make up proteins. They have various physiological activities for the human body and can participate in human metabolism and supplement nutrition.
In terms of trace elements, it contains calcium, phosphorus, iron, etc. Calcium is essential for maintaining physiological functions such as bone strength, nerve conduction, and muscle contraction in the human body; phosphorus participates in energy metabolism and acid-base balance regulation in the body; iron is the key raw material for hemoglobin synthesis, which is of great significance to oxygen transportation and cell respiration.
Compared with humans, the human body is composed of a variety of cells, tissues, and organs. At the physical level, it has complex morphological structures and motor functions. Chemically, the human body constantly undergoes various biochemical reactions to maintain life activities. Although turtle armor and humans have different compositions, its active ingredients can have a regulatory effect on human physiological functions when combined with medicinal uses. Such as turtle armor into the liver meridian, can nourish yin latent yang, soft and loose knots, human liver physiological function echoes, can improve the human body Yin deficiency and Yang hyperactivity, the accumulation of evil and other pathological states.

The servant is also a servant who serves in the service of others. However, the servant is in the process of service, there are all kinds of safety risks.
One, the risk of injury. The servant's daily work, either for the sweeping court, or for the cooking and cleaning. When cleaning, climb high places to wipe the dust, if the foot slips and leans, it is easy to cause falling injuries, the skin is broken and the flesh is broken, and the serious is broken. As for the cooking and cooking, it is close to the stove fire candle, hot oil and boiling water are often accompanied, and if you don't pay attention, you will suffer from burns.
The second is the worry of infection and illness. The servant is in someone else's house, and everyone depends on him to manage their daily life and diet. If the head of the family is infected with an epidemic, the servant is close to the servant, and is very vulnerable to its infection. Moreover, the servant works hard, does not work and rest often, and the diet is also rough and simple. In the long run, the accumulated labor becomes a disease, the viscera are vulnerable, and the chance of contracting the disease is greatly increased.
Third, being bullied. Although he is a servant, there are also people who are ill-intentioned. The servant is weak and helpless. If he encounters a tyrannical master, he will be beaten and scolded if he is slightly wrong. What's more, he has bad intentions and acts indecent to the servant, causing physical and mental damage, and the servant often has no way to complain and can only swallow it.
Fourth, the suspicion of theft of property. The maidservant travels frequently in the family, and has many opportunities to come into contact with property. If the property in the family is lost, the maidservant is often easily suspected. Even if it is not stolen, it may be interrogated, reprimanded, or even beaten into a confession by the master family, and it will be unjustified.
All these security risks follow the maidservant in the process of serving, making his livelihood difficult, physically and mentally exhausted, and he is a pitiful and pitiful person.

In "Tiangong Kaiwu", the method of making candles is to use tallow or white wax.
If you want to make a candle, take the tallow first. Choose a good cow to slaughter and take its fat. Put the fat in the kettle and boil it slowly. When boiling, you need to stir it frequently to make it evenly heated. When the fat is completely melted, its residue is removed, and pure tallow is obtained.
If you use white wax, the white wax is taken from the wax formed by the wax worm. After picking the wax, it is also melted in the kettle to remove impurities.
When making candles, use cotton thread as the core, and the thread should be straight and moderate in thickness. Fix one end of the core on the candle mold, which is mostly a bamboo tube or a special mold.
First heat the tallow or white wax until it is completely melted, slowly pour it into the candle mold, so that the melt flows evenly along the core. When it is slightly cold, the liquid gradually solidifies, and then carefully observe the candle shape. If there is any inappropriateness, you can add the melt.
When the candle is completely solidified, carefully take it out of the mold to get a candle. In this way, according to this 1:1 method of candle, a suitable candle can be obtained for lighting needs.
