The golden "snake" symbol in the middle of the health code is a walking stick with a snake pattern wrapped around it, which is scientifically called snake stick and used as a medical symbol. There are two kinds of medical marking systems 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' wand in Greek mythology. A snake's cane is the main symbol of Asclepius Ashibis, the god of medicine in Roman mythology.
