The main uses of ramie are wide. First, it is a good textile material. The ramie fiber is slender and tough, shiny, strong and fast in moisture absorption and heat dissipation. The ramie woven cloth is cool and breathable, comfortable to wear, especially in summer. The ancestors of ancient times often took ramie fiber and made exquisite ramie cloth through various processes such as polished hemp, spinning, and weaving. It can be used for daily clothing or as a towel.
Second, it can be used for papermaking. The ramie fiber has excellent texture, so the paper is tough and smooth, suitable for writing and painting. The masterpieces of many scholars and writers in the past, or written on the paper made of ramie, have been passed down through the ages. Its fiber characteristics make the paper durable, not easy to be damaged or moth-eaten, which is of great value to cultural inheritance.
Third, it also plays an important role in the preparation of ropes. Ropes made of ramie are strong and wear-resistant, and are widely used in production and life. Such as bundling goods, building scaffolds, mooring ships and berthing, etc., all rely on its strength. Its excellent performance ensures the smooth progress of all kinds of labor and provides a solid boost for social production.
Fourth, ramie also has certain value in the field of medicinal use. According to ancient records, ramie roots and leaves can be used as medicine, with the effects of clearing away heat, diuretic, stabilizing fetuses and hemostasis. In case of corresponding diseases, doctors may use ramie as medicine to heal diseases and escort the health of the people.

Lead and mercury are spiritual objects between heaven and earth, each of which has its own unique physical properties. They are important in the fields of alchemy and craftsmanship, and were carefully observed and distinguished by ancient Chinese sages.
Lead is black in color and heavy in quality, and has a sinking sex. "Hardware Art" says: "Lead is the righteous energy of the north, and the essence of the cathode." Its shape is soft and can be cast and formed at will. This characteristic makes it very popular in casting processes. For example, swords and cauldrons are made of lead, which is malleable and can be transformed with the shape of the tool. And lead has a low melting point. In the fire, it is easy to melt into liquid. "Baopuzi" states: "Lead is easy to melt, and it flows when it encounters fire." This point is convenient for ancient craftsmen to operate and cast all kinds of utensils. Furthermore, lead has good corrosion resistance, and it is not easy to rust and rot when left for a long time, so it is often used to make containers, which can be preserved for a long time.
Mercury is different from lead, it is a liquid metal, often silver-white light, flowing and flickering, like a spiritual thing. "Tao Shu · Mercury and Lead" says: "Mercury is the essence of yang, and its nature flows." Mercury is very volatile, and at room temperature, it can gradually turn into gas, dissipating and formless. "Compendium of Materia Medica" says: "Mercury, if scattered on the ground, is pervasive, and when heated, it quickly turns into gas." This volatility makes mercury have a high status in alchemy cultivation. Alchemists believe that mercury contains innate spiritual energy, which can help refine elixirs when it evaporates. At the same time, mercury has a high density, which is heavier than many common liquids. This physical property makes it particularly effective for the analysis and balance of physical states.
Lead and mercury, one sinks and one floats, one solidifies and one liquid, are opposed to each other and depend on each other. In the process of ancient people's exploration of nature, pursuit of longevity, and creation of utensils, they left a profound imprint and added a bright chapter to the treasure house of Chinese civilization.

The combination of lead and mercury has been studied by ancient alchemists for a long time. There are three ways to obtain the method of combining lead and mercury.
First, the method of sublimation. Take an appropriate amount of lead and mercury, put it in a closed device, and slowly heat it with a slow fire. Lead and mercury are sublimated by heat and condensed on the wall of the device to obtain the essence of the synthesis. This process requires careful temperature control, so as not to make the fire fierce and cause the lead and mercury to escape. If the heat is suitable, the compound is pure and effective.
Second, wet synthesis. Use acid as a medium to dissolve lead and mercury. The acid can break the quality of lead and mercury and make it ionic. Then, add a neutralizing agent to precipitate the compound. The choice of acid solution is very important, and it depends on the nature of lead and mercury and the quality of the compound you want to obtain. And when operating, when the anti-acid solution hurts people, be cautious.
Third, catalyze with medicinal induction. Find special medicinal induction, and combine lead and mercury to refine. Medicinal induction can promote the synthesis of lead and mercury, reduce the required energy, and improve the rate of synthesis. However, medicinal induction is rare, and it is mostly a secret recipe, or hidden in ancient books. Alchemists often traveled through mountains and rivers, visiting strangers, in order to obtain such medicinal induction methods.
The synthesis of lead and mercury is related to heat, agents, and medicinal induction, all of which are subtle studies. The ancients were here for years and years to study the wonders. Although there were absurdities, there were also many insights, which left a lot of information for the future generation of chemistry.

Mercury is a highly toxic substance and is similar to lead. When storing and transporting mercury, many matters must be handled with caution.
Those who store mercury should be sealed first. Mercury is highly volatile, and its vapor is highly toxic. If it escapes in the air, it will be very harmful to human health. Therefore, it must be stored in a strong and well-sealed container, such as a special thick-walled glass bottle, and the bottle mouth must be tightly sealed to prevent mercury gas from leaking out.
Furthermore, the storage place should be cool and dry. Mercury is prone to accelerated evaporation when heated, and humid environments may cause the container to rust, which will damage its sealing. It is advisable to choose a well-ventilated and non-heat source place, away from direct sunlight and high-temperature equipment.
As for the transport of mercury, the packaging must be firm. In addition to the inner sealing container, the outer layer should be wrapped with a cushioning material, such as thick foam or cork, to prevent vibration and collision during transportation, and prevent mercury leakage due to damage to the container.
During transportation, temperature and humidity should also be strictly controlled. If it is transported in high temperature seasons, there should be cooling measures, such as refrigeration equipment or ice packs to cool down. And the transportation vehicle should run smoothly to avoid sudden braking and bumps to reduce the risk of damage to the container.
Once there is a mercury leakage, it must be handled quickly and carefully. Evacuate the crowd first, isolate the scene, and strictly prohibit unrelated people from approaching. Subsequently, sulfur powder is sprinkled on the leakage, and mercury and sulfur can be synthesized into mercury sulfide, which is greatly reduced in toxicity. After collecting mercury sulfide, properly dispose of it and do not discard it at will.
The storage and transportation of mercury is related to everyone's safety and environmental safety. Every link should not be ignored. It must be carried out in accordance with strict laws and procedures to ensure safety.

Vermiculite, that is, earthworms, often breed in fertile soil. They are good at cutting soil, and they feed on decay and other materials, which makes the soil better.
Leeches, are leeches that often live in freshwater waters such as paddy fields, canals, and ponds. They mostly feed on the blood of other organisms, and some of them feed on plankton and small animals in the water.
Both worms and leeches are natural animals, but their lifestyles and survival environments are slightly different. Worms come out at night and like to live in the soil; leeches live in water more, and have a certain adsorption capacity, which can attach to other organisms.
To A, they are often breeders. Such as gold seeds, their larvae are mostly found in soil or rotting wood, and they feed on the roots of rotting plants. The product is mostly eaten by nectar, juice, etc.
Another example is scoop, some scoop larvae feed on small kun such as aphids, and the larvae also feed on aphids, insects, etc., which are beneficial. It mostly lives on aphid-breeding plants.
Another example is walking, and the larvae are carnivorous and prey on other small kun. It is often found in tidal piles, soil surfaces, etc.
As such, leeches, leeches, and polycarnivores each have their own specific breeding environment and food source, and play different roles in the biological system.
