What is the main line of "the mountain is high and the road is far"

The mountain is high and the road is far. Wang Guozhen's crying is the outbreak of silence. Silence is a silent call, whether it is agitation or tranquility. I pray that as long as I am not bored, if I am called from afar, I will go to towards the distant. If the mountain calls me, I will go to the mountain, and my feet will be worn out. Simply let the sunset smear the road, and my hand will be scratched. Simply turn thorns into azaleas. There is no longer road than feet. There is no mountain higher than man. The mountain is high and the road is far, which is the representative work of Wang Guozhen's poetry. This poem expresses an enterprising, persistent, optimistic and confident emotion, and shows the fighting, enterprising, high-spirited and uplifting spirit of contemporary youth, and draws a clear line with those moaning decadent voices and those empty and boring rhetoric poems. It inspires people and gives them healthy and upward spiritual guidance, thus winning the love of the vast number of young people. In lyricism, we don't rely on obscure words or even exaggerated and distorted images to express our feelings, but mainly focus on image discussion. Discussion is the main means of lyricism here, but it is different from those dry sermons. It turns abstract thinking into a novel and beautiful image, and implies emotion in the discussion of the image. For example, "My feet are worn out/I just let the sunset stain the path/scratch my hand/I just let the thorn turn into a cuckoo", which is the hardships and twists and turns encountered in the process of writing struggle. My feet are worn out and blood is spilled on the path; Scratched hands, blood-stained thorns, this is a portrayal of the strugglers. But the author turned pain and even suffering into beautiful images-brilliant sunset and beautiful cuckoo, thus expressing his contempt for suffering and optimistic attitude to overcome it. For example, although "the mountain is high and the road is far", "If the distance calls me/I will go to the distance/if the mountain calls me/I will go to the mountain" is also good. I want to "cross myself", "I won't be sad as long as spring is still there" and "I won't be sad as long as life is still there"!
