Two snakes coiled around a needle with wings at the tip, does anyone recognize this pattern? It should have something to do with medicine.

The cross, which symbolizes medical care, will be withdrawn from the 120 emergency network. Instead of the blue snake staff, the blue snake staff through the Star of Life, meaning to save lives. 120 front-line emergency personnel and ambulances, will be fully dressed, whether it is the body of the ambulance, emergency doctors, nurses, winter clothing, reflective undershirts, concierge uniforms, spring and autumn clothing, will be in the obvious parts of the new logo.

Related first aid stations will also unify the logo

For the first aid personnel dress, before 1997, the 120 first aid personnel's uniforms are simply white coats and white pants; in 1997, the first aid doctor to wear a chest printed with "** First Aid Center," the word of the white jacket; in 2002, the beginning of the blue logo printed on their clothes.

The Snake Staff as a Medical Symbol

There are two major systems of medical symbols in the world: one is the double-snake-wrapped staff with two wings standing on top as the theme, and the other is the single-snake-wrapped staff as the theme. The double-serpent, double-winged staff is derived from the wand of Hermes/Macri, the messenger of the gods in Greek mythology. The single-serpent staff is the main symbol of the Roman god of healing, Achilles. Traditionally, the single-serpent wand has been considered to be the orthodox medical symbol. Whether it is a single-snake staff or a double-snake staff, both imply the meaning of "sex", indicating that the root of healing comes from the miraculous power to create life, which can be corresponded to by the Sanskrit word Kundalini, which is translated into Chinese as "spiritual quantity". In short, the snake staff symbolizes magical healing and neutral medical ethics.

Hermes, the messenger of the gods

Hermes, the messenger of the gods in Greek mythology, was the son of Zeus and Maia. He was in charge of business, travel, and athletic training, and even included stealing, which in general meant that he was in charge of all the activities that required skill and dexterity. He was a messenger of the Greek gods, wearing a hat with feathers on his head, shoes with feathers on his feet, and a wand with two serpents wrapped around it (Caduceus), which had the effect of hypnosis, and once Zeus commanded Hermes to put his mistress's guardian, the hundred-eyed giant Argus, under hypnosis, using this wand.

Mercury in Roman mythology

In Roman mythology, Mercury is the equivalent of Hermes in Greek mythology. Mercury, the messenger of Venus on the far left of Botticelli's famous painting "Spring" in 1480, uses a wand with a serpent wrapped around it to ward off the clouds, so that the garden of Venus will always have eternal spring. He is said to have invented the lyre, an ancient plucked string instrument. One day he found a tortoise, removed its shell, drilled holes in the rim, and threaded linen thread through the holes, and the new instrument was born. The thread was divided into nine strands in honor of the nine Muses, who held the power of literature and the arts. Mercury offered the lira to Apollo, the sun god, in exchange for the magical serpent staff (Caduceus). Also, the word Mercury is the planet Mercury of the nine planets as well as the chemical element mercury.

Meaning represented by the double serpent staff

The double serpent staff (caduceus; Greek karukeion), the symbol of Hermes/Macri, the messenger of the gods, also represents the herald's rod, with two serpents entwined to the left and right, their heads facing each other, and a pair of angelic wings at the top of some of the staffs. In modern times, the double-serpent staff is seen as a symbol of the trade and transportation industry, as well as medicine, and alchemy. There is also a legend that when Macri threw his staff between two snakes that were biting, the snakes were reunited. Therefore, the double-snake staff is also regarded as a symbol of peace.

Asclepius

Asclepius (Latin aesculapius) was the god of medicine in Roman mythology. He is depicted holding a wooden rod entwined with a spirit snake. Why did the Greeks associate this symbol with medicine? Because snakes shed their skins every year, which was always considered a process of restoration and renewal. The stick represents the vertebrae of the human body, which is also the location of the middle chakra. It represents the activity of the spiritual energy as it rises along the middle chakra in a double helix. Coincidentally, this double helix pattern of spiritual energy activity is very similar to the structure of the DNA molecule, which is the genetic material of the human body. In ancient times, especially in the hospital located in the medical spa, the snake is revered as a sacred object. It is said that when ancient Rome was ravaged by the plague, the people brought in Achilles, who was disguised as a giant snake, and the plague immediately disappeared.

Nele?

The cross with a serpent nailed to it, as seen in "Purgatory of Steel," is in fact the work of Nicholas LeMay, a 14th-century French alchemist. The cross of Nicholas Flamel, the man who created the Sage's Stone. Alchemy first came from Egypt, and the great medieval alchemist Geber (Geber 721- 815, originally a physician) published a considerable number of books on the subject, and most scientists of the time agreed with Geber's hypothesis that all metallic substances belonged to the same species, since they all evolved from the ideal forms of mercury and sulfur. All metals could therefore be transformed into each other under the right technical conditions. Alchemists could, by means of the "Sage's Stone", refine metals such as iron, copper, lead, tin, etc., into silver and gold. Minerals plus blood, hair, feces, and other various substances, after various chemical reagents, and then through the basic process of smelting, sublimation and distillation, the essence can be extracted to be refined and purified, through this long period of refining process, some people claim to be made into a panacea for longevity, and some people claim to have been refined into gold, which is the basic concept of alchemy. Later on, Niels Henrik Lemay made mercury and sulphur into gold, which was the basic concept of alchemy. LeMay took the ideal form of mercury and sulfur, a serpent wrapped around a cross with a pair of wings and a crown on top, as the basic symbol of Western alchemy, with the idea of the cycle of generation of all things in the world.

The power to bring the dead back to life

The cross represents the Tree of Life/Tree of Wisdom in Christianity. Because Eve was seduced by the serpent and tasted the forbidden fruit, which led to the expulsion of Adam and Eve from the Garden of Eden, and they took the responsibility of giving birth to the child, and suffered from the pains of pregnancy for the rest of their lives, the serpent wrapped around the Tree of Wisdom represents "sex", which is also the origin of life. The cross also symbolizes salvation because Jesus was crucified and rose from the dead three days later, so the cross also represents the power to heal and raise the dead. The New Testament writes: "As Moses lifted up the serpent in the wilderness, so the Son of Man has been lifted up, so that whoever believes in him shall not perish but have eternal life.
