Like human beings, snakes have their culture and value in the long river of historical development. Especially in the eyes of writers at home and abroad, snakes have many unique images. In ancient times, the snake was once a sacred object praised and worshipped. The dragon, the largest "divine thing" in China, is the totemic product of the snake.
Cobra is the general name of some snakes in cobra family, mainly distributed in tropical and desert areas of Asia and Africa. The most obvious feature of cobra is the neck, where the ribs can expand outward to intimidate the opponent. When the neck expands, a pair of beautiful black and white spots will appear on the back, which looks like Cobra patterns, so it is called Cobra.
