After the death of the old King Lennar, the Northern Territory was plunged into a shadow of conspiracy and tyranny, and the people were miserable. The aristocratic class monopolizes power and tyranny is rampant. The fruits of farmers' hard work are wantonly plundered. Workers are squeezed in the workshops. The common people have no food and clothing, and no dignity at all. The entire northern border is filled with depression and despair. Class conflicts are becoming increasingly acute. The fire of change is quietly gestating. Shuangdong rose up with a group of like-minded people. After going through power struggles, class games and persistence of ideals, they overthrew the old noble rule and implemented an enlightened new deal. During the process, they went through many hardships and dangers. They had to face the brutal suppression and conspiracy of the Xungui Group, and smash the sieges and plots against the revolutionary forces. They also had to resolve internal differences and wavering, adhere to their ideals and beliefs, unite people with perseverance, and gradually strengthen the revolutionary ranks in the test of blood and fire. They eventually overthrew the old rule and ended the era of Xungui's dictatorship. After the New Deal was implemented, the foundation of the northern border gradually stabilized, and farmers and workers lived and worked in peace and contentment. The teacher's wife is deeply involved in the folk work, using materials from her daily work to compose down-to-earth songs and dances. She uses string songs to convey people's expectations and enlightenment thoughts. The songs and dances spread throughout the northern border to unite people's hearts, and ultimately witnessed the victory of the New Deal. The northern border has ushered in long-term peace, the mountains and rivers are intact, and string songs will last forever. After the soul of the old King Lennar returned to Jiangchuan, Shuangdong took the lead in implementing the New Deal, which was people-oriented, focusing on improving people's livelihood, rectifying order, and injecting new vitality into the northern border. Under the New Deal, farmers' fields ushered in a bumper harvest, workers' workshops were revitalized, schools were opened everywhere, and people were relieved of the burden of harsh governance and lived a stable and prosperous life. The wind in the north was filled with the warmth of fireworks after the haze of power had faded away.
