Who is the author of this labor poem?

Song of Laborers: Yang Jun (Xuzhou) is near the first festival in May, just like the feeling of catching a train for the first time: when waiting for the bus, it feels that the car is driving very slowly and far, but when approaching, it is shocked by its roar and speed, and the expectation is full of joy and confusion! There is also temptation: laborers' festivals are full of laborers' songs. Standing at the beginning of May, we saw the workers waving their arms, like jumping notes in the sun, falling carelessly, touching the sleeping land in spring and turning a long green. Suddenly, workers' songs rang out inside and outside the Great Wall and on both sides of the Yellow River, echoing in the hearts of hundreds of millions of workers, echoing between blue sky and white clouds, echoing on 9.6 million square kilometers of land, knocking down a tree and bird in the early morning when red flowers spread. Workers' songs praise the fruits of harmonious China's labor. The beautiful scenery is full of eyes, singing happily under the notes flying at a new speed, spreading all over China at a speed of 350 kilometers per hour, bringing good news from Beijing and giving busy workers hope for life. As a result, we can see that railway workers have become road guards laughing in the wind on both sides of the railway, making the solid rails full of poetry and painting; Then, we heard the songs of labor resounding through the sky, accompanied by the long whistle, galloping all the way on the track in spring and singing forever; As a result, we received notes floating in the blue sky, which are the sweet songs of fruitful construction that ordinary workers constantly arch from the foundation of high-rise buildings ... The songs of workers are blue, magnificent and shocking symphonies written by workers' dreams. 5,000 years of Chinese civilization has been fixed in the brilliant chapters of Tang poetry and Song poetry with the songs of laborers, burning in the rolling mountains of * * * and China, echoing in the fragrance of wild grass seal script, roaring in the smoke of pioneers, and passing on in the happiness of trekkers. Perhaps, after a thunder, the heavy rain came, the majestic song was loud, and the geese flying south waded home; Perhaps, the majestic singing is that apricot blossoms bloom all over Shan Ye. When the spring breeze blows through vilen in the brilliant season of "She laughs among the flowers", the harmony of winter wheat farmers sweating and hoeing rhymes with the good times of hard work ... The singing of laborers has crossed the hustle and bustle of the city and landed on the towering roof; Workers' songs have crossed the countryside and soared on the modern information highway; The songs of laborers have crossed the mountains and rivers, turning the vast land into a small village and the vast wasteland into a thousand acres of fertile land. When it rings in the workshop, it produces the roar of splashing steel flowers and impacting the machine tool; When it sounded on the front line, it was carved with the muscles and copper breasts raised by the workers' master; When it rings on campus, it sets off the light of knowledge, exchanges the wisdom and dreams of books and people, and moistens the flowers of the motherland with the sweat of gardeners ... Oh, the songs of laborers, the most beautiful and moving music in the world, are singing gently, which sounds like mountains and rivers laughing. In the tall building outside the building, in the pavilion outside the pavilion, holding hands is even more heroic. Workers' songs are beating the long coastline, the melody of reforming Hong Zhong, touching the heartstrings of the times, singing with the strong voice of * * * and the country, and singing with the harmonious society, playing the song of scientific development that keeps pace with the times, focuses on development and inspires people in the new era! Sing the song of labor, please let us pay tribute to the workers! Sing for the workers! Applause for the workers!
