What is the function of the oak tree? "Roots are firmly rooted in the ground and leaves touch in the clouds."

The poet takes the oak tree as the object, expressing the passion, sincerity and loyalty of love. The oak tree in the poem is not a concrete object, but a symbol of the poet's ideal lover. Therefore, this poem is not simply to pour out his passionate love, but to express an ideal and belief of love, which is quite meaningful to the ancients through a kind and concrete image.

1. First of all, the oak tree is tall, charming, deep and rich in connotation-"high branches" and "shade" are the same meaning, and the method of setting off is adopted here. Poets don't want arty love, and don't want to be a conspicuous Campbell, attached to the high branches of oak trees and complacent. Poets also don't want to give charitable love. Don't want to be a mountain that blindly supports oak trees. The poet doesn't want to lose himself in such love. Love needs to be based on equality of personality, independence of personality, mutual respect and admiration, and mutual affinity.

What the poet wants is the kind of love that two people stand shoulder to shoulder and share weal and woe together. The poet compares himself to a kapok, a kapok standing side by side with an oak tree. The roots and leaves of these two trees are closely connected. The poet's persistence in love is no less than the ancients' "I would like to be a lovebird in the sky, and I would like to live together on the ground, with two branches in one tree." . Oak and kapok stood quietly and firmly, the wind blew, swaying branches and leaves, greeting each other, and then their hearts were satisfied.

These two people are such guardians, two determined trees, two fresh lives and two noble hearts. Like a brave guardian, every branch is always ready to stop attacks from the outside world and defend its own world; One is a passionate life, with red flowers, willing to cheer for him and light up his future when he is struggling. They share the threat of difficulties and the test of setbacks; Similarly, they enjoy the splendor of life and the magnificence of nature.

What the poet wants is such great love, the same greatness and nobleness, the same thought and soul, rooted in the same foundation, sharing weal and woe, and being dependent on cold and warm.

5. Poetry expresses the poet's ideal view of love with novel and magnificent images and appropriate metaphors. The metaphor and peculiar image combination in the poem represented the new form of poetry at that time, which was of groundbreaking significance. In addition, although the novel images are used in the poem, the language of the poem is not obscure, but colloquial, with fresh aura and subtle hints, giving people unlimited room for reverie.
