120 There is a sign on the ambulance, and a snake is wrapped around a stick. How did this happen? What does this mean?

Western medicine takes "snake stick" as its symbol. The so-called "snake stick" is a walking stick with a snake-shaped pattern around it. Here is an anecdote, which originated from an ancient Greek legend: Askero Pia, one of the founders of ancient Greek medicine, is said to be the son of Apollo, the sun god, and Coroni, a mortal. He once studied medicine with Khyron's superb medical skills, and his medical skills were very good. One day, while he was thinking about a case, a poisonous snake crawled over and wrapped around his hand. Askero Pia was surprised and killed the poisonous snake at once. Unexpectedly, another poisonous snake appeared, with herbs in its mouth, lying next to the dead snake. The dead snake came back to life. Seeing this scene, Askero Pia immediately realized that snakes are poisonous and can kill people, but they have mysterious healing power and can save people. No wonder people always think that snakes are the embodiment of wisdom. From then on, every time Askero Pia went to practice medicine, he not only had to carry a war snake with him, but also always wrapped a coiled snake around his cane. Once this theory spread, people engaged in the medical industry followed suit, so the "snake stick" became the symbol of the western medical industry. In the old society, the collar of the Kuomintang military medical officer was the badge of "snake stick". As a medical symbol, snake sticks have two major medical symbols in the world: one is a double snake stick with wings as the theme; The other is about a snake wrapped around a stick. The double snake-winged staff originated from Hermes/macri's wand in Greek mythology. The staff of a single snake is the main symbol of Ashibis, the medical god in Roman mythology. Traditionally, people think that a snake's walking stick is an orthodox medical symbol. Whether it is a single snake stick or a double snake stick, both of them imply the meaning of "sex", indicating that the root of healing and healing comes from the magical power of creating life, and Kundalini in Sanskrit and the "spiritual quantity" in Chinese translation can correspond to it. In short, the snake stick symbolizes magical medical skills and neutral medical ethics.
