The second ointment is a good medicine of ancient times, and its main users are multi-end.
First, it treats sores and swollen diseases. Sores start at the beginning, red, swollen and hot, and qi and blood are stagnant. The second ointment is applied to it, which can dissipate its congestion and relieve its swelling and pain. Cover this ointment with the ability to promote blood circulation and remove blood stasis, clear heat and detoxify, so that qi and blood can flow smoothly, and the heat poison can be relieved. If carbuncle starts, apply the second ointment to the affected area, which can gradually eliminate the swelling, ease the pain, and prevent pus from breaching, and relieve the suffering of patients.
Second, treat bruises and injuries. For those who cause blood stasis on the skin and pain in the muscles and bones due to falls and collisions, the second ointment It can dissipate blood stasis, clear the meridians and collaterals, and relieve the tendons and veins. The application of this ointment to the injured can help the blood stasis dissipate, promote the repair of damaged meridians and collaterals, make the pain stop gradually, and the limb activities return to normal.
Third, it also has strengths in the disease of itchy skin. Wind evil invades the skin, or damp heat accumulates the skin, causing itching to be unbearable. The second ointment has the effect of removing wind and dampness and relieving itching. Applying it can make the skin comfortable and the itching gradually subsides.
Fourth, it can be used for some skin ulcers that do not close the mouth for a long time. The second ointment can generate muscle and close the mouth, improve the local qi and blood operation, promote the growth of new
In general, Erxuan ointment can often play a significant role in surgical diseases due to its various effects, such as dissipating swelling and reducing carbuncle, promoting blood circulation and relieving pain, removing wind and relieving itching, or generating muscle and astringent sores. It is also a common prescription for doctors to treat diseases.

The two-kick is a traditional folk firework, and its physical properties are quite unique. The two-kick is composed of two upper and lower chambers, which are sealed with soil.
First of all, in terms of quality, the overall weight of the two-kick is relatively light, which is easy to hold and discharge. Its shell is mostly made of paper or simple materials, which reduces the overall weight, but also ensures that the structure is stable during discharge and resists the force generated by the explosion of internal gunpowder.
Secondly, from the perspective of inertia, its mass is not large and the inertia is small. During the launch of the discharge ejection, it is easily affected by external forces to change the state of motion. When the bottom gunpowder ignites and explodes, a strong thrust is generated, which can quickly overcome its own small inertia, break through the air resistance, and quickly lift off.
Furthermore, in terms of energy conversion, the bottom gunpowder contains chemical energy. After igniting, it burns violently, and the chemical energy is quickly converted into internal energy. This internal energy is converted into mechanical energy of the two kicks in a very short time, which prompts it to move upward. After rising to a high altitude, the gunpowder in the upper chamber is ignited, and energy conversion occurs again, releasing a large amount of internal energy, which is displayed in the form of sound and light, emitting loud noises and strong light.
In addition, the aerodynamic properties of the two kicks are also worth mentioning. Its shape is usually slender. During the lift-off process, this shape can effectively reduce air resistance, reduce energy loss, and allow more energy to be used to raise altitude and produce subsequent explosion effects. When traveling through the air, it can maintain a relatively stable flight trajectory, despite being disturbed by factors such as airflow, but it can generally move in the expected general direction, providing a unique visual and auditory experience.

Eran, its nature is strong and strong, among all kinds of substances, it is quite special.
From its shape and quality, Eran has a material that is dense and tough. Its quality is like the condensation of gold and stone. Although it is not as hard as gold and iron, it is unique in its flexibility and anti-damage strength. Looking at its texture, it is delicate and orderly, like a brocade woven by heaven. This texture is not only beautiful decoration, but also contains the stability of its internal structure. Therefore, the material of Eran is not easy to deform due to slight external force under normal conditions, and can maintain its inherent shape for a long time.
As for its chemical properties, it is also quite stable. When encountering all kinds of ordinary chemical reagents, Eran seems to be able to resist its erosion. Immersed in water, it is insoluble and incorruptible, just like a stubborn stone standing in a torrent, and it is not melted by water waves; during fire, although the surface may change, the core can still maintain its essence and will not be turned into ashes like ordinary wood. This is because of the delicate internal structure of Eran, and the strong intermolecular support, making it difficult for external chemical reactions to easily break its original structure.
In a complex chemical environment, Eran can also handle it calmly. Acid and alkali agents have little effect on it. Acid droplets on it are like morning dew falling on hard rock, which is difficult to corrode its body; soaked in lye, it is just like a breeze, without damaging its quality. The stability of this chemical property makes Er An able to withstand wind and rain without being destroyed over the years. Under the changes of nature and the action of chemistry, it always maintains its own characteristics, which is a rare wonder in the world.

The first thing to pay attention to when it is hidden is that it is hard to hide. If it is too long, it is easy to cause corruption. If it is not used for a long time, it is easy to invade, and the material is easy to be used, and it is durable. Therefore, it is appropriate to set it in a place where it is difficult to communicate, so that it can be placed in a place where the water is tidal, so that it can be guaranteed to be intact and extended for use.
Furthermore, it is also necessary to prevent it. If you like to eat it, you often eat it in the dark, causing it to break. You can use it to hide, and put some dirty things, such as the one in the Camphor Pill, so that you can't come near, so that you can be complete.
Until it is fixed, it should be fixed first. If it is not properly fixed on the way, it is easy to shake and collide, resulting in damage to its shape. It is advisable to ask for it, or put it in a container for use, to make it safe.
And the equipment of the machine is also cleaned. If there is something left on it, or stained the second machine, it will affect its use. It is difficult to protect it from exposure to the hot sun. The intensity of sunlight can make the material age and brittle, which affects its performance.
It is necessary to pay attention to the things that need to be hidden, such as dryness, prevention, fixation, avoidance, and equipment cleaning, so as to ensure that they are always available and help.

The two aspects involved in the environment are important and important. The "Heavenly Works" has not yet been completed. The shadow of the second environment, however, it is mentioned that the general work and things can be explained by us.
The second aspect of the husband's life is also the cause of the burning things. Its source is wide, and it can be caused by industrial construction, people's livelihood cooking, etc. The "Heavenly Works" is like the key, such as manufacturing, using charcoal fuel to burn. The burning of charcoal, put a lot of waste, float in the air, and cause air pollution. And it may contain sulfur and other waste, burning and generating harmful waste such as sulfur dioxide. If it does not disperse, it will affect people's lungs, and it will also build utensils.
In the past, firewood was used more often, and firewood was burned out. In the room, people who have lived for a long time are smoked by it, and their breathing is also affected by it. In the village, if the family cooks and rises, if the settlements are dense, it will cover the environment and shadow the surrounding air.
In addition, if the second one falls on the ground and plants, the lightning will adhere, which will affect the photosynthesis of plants and inhibit their growth. If the poison and harmful substances in the soil enter the soil, it will also affect the soil fertility, damage and crop.
The "Heavenly Works" does not describe the harm of the second environment, but according to common sense, the ancient work and activities, or daily living, the second environment has been invaded, and there are adverse effects on air, plants, and soil. The ancients did not know about it, but they also felt its inconvenience.
