In 1973, Lin Yuan traveled across time and became an educated youth in Qinghe Village. Without a golden finger, he only relied on modern knowledge and hard-working hands to write legends on this land. Starting from improving farm tools and cultivating fine seeds, he gradually led the villagers to develop the courtyard economy and set up factories, turning the barren mountain village into a model of prosperity. Facing the tide of returning to the city, he stuck to his original intention and joined hands with the beautiful woman Su Wanqing to use his wisdom and sweat to cultivate the prosperity of an era. See how Lin Yuan realized the perfect integration of personal values and rural changes in the turbulent years, and composed a leisurely and moving pastoral hymn.
