The Lord of the Rings: The Two Towers

After watching The Two Towers, the battle scene was magnificent, but it was no longer moved by many lines like the first The Fellowship of The Ring.

However, there seems to be some thoughts on the reflection of each race, even the representative role in each race.
Are all the colorful characters in the Lord of the Rings the reflection of some characteristics or identities in our real world?

Hobbit, a child, has childlike simplicity, is satisfied with what he has (food, manor), and satisfies some desires (appetite, sleep) with the simplest foundation. Therefore, without the temptation of the Lord of the Rings, the desire for power to rule the world is useless to them, instead, they become the holders of the Lord of the Rings.

Thinking: whether we can hold a simple heart like a child in our life, hold it but not possess it, and deal with the complicated and tempting world with a simple heart.

Mages-elders (priests) have accurate foresight of future events. Have the ability to spell, fight against dark demons, and be promoted continuously in this victory (Gandalf, the gray robe mage, became the white robe mage after defeating efreet). Will fall in temptation (Salaman). Thinking: priests have eloquence, knowledge, teaching and discrimination, and can fight against the dark forces to win. But ability is not everything. He may degenerate and change this ability from creating people to misleading people (heresy)

Elves-Angels have eternal life, but they also fall. Can talk with trees, birds and animals and think: eternal life may still be lonely without love. People can not lack love

Human beings-human beings are noble, proud, respect authority (king), attach importance to honor, have ideals (trust), hope (hope) and love, and protect their loved ones to the death

Orcs-wicked people who live for their own desires, are cruel and rude, and do everything for themselves. Has sold his soul to the evil one.

Dwarf-a humble person with great energy. Humorous, simple, kind and competitive
