What is the classification of Harry Potter schools?

Hogwarts is divided into four colleges, namely Gryffindor, Hufflepuff, Ravenclaw and Slytherin. Gryffindor stands for fire, Ravenclaw stands for wind, Hufflepuff stands for earth and Slytherin stands for water. When the four elements coexist, a complete system is formed.

Admission criteria of Harry Potter's four colleges

Gryffindor admission criteria: fearless and desperate. Fearless and adventurous. Fire-like personality and fire-like color, the Weasleys' hair is red, and Dumbledore, the owner of the fire phoenix fox, also graduated from this college.

Hufflepuff chooses students in a diligent and honest way. Color basically belongs to the color of the earth. Badger is a burrowing rodent. A simple and honest badger is portrayed in the fairy tale of willow trees on the river bank. Rowling liked this book very much when she was a child. Badge basically covers that people who enter Hufflepuff are as honest and loyal as badgers.

The tenet of Ravenclaw College: wisdom, justice, shrewdness, erudition, intelligence, foresight, strong curiosity and love to study things. The eagle and the blue sky are symbols of the wind. This university is characterized by its intelligence and wisdom. Sorting hat commented that "if you are smart, you may enter the smart old Ravenlock, where those smart and knowledgeable people will always meet their colleagues".

Slytherin admission criteria: the shrewd Slytherin came out of that quagmire, and he likes those teenagers who are pure in blood, ambitious and eager for power best.
