In Qingshi Village, Lin Dashan, Lu Tianhao, and Zhou Zikai swore a oath of brotherhood in their youth to share weal and woe. Lu Tianhao and Zhou Zikai went out to work and start a business, while Lin Dashan stayed behind in their hometown, silently caring for their ailing elders for eight years. When his wife Shen Xiulan suddenly fell critically ill and urgently needed half a million for surgery, the proud Lin Dashan was reluctant to burden his brothers and found it hard to speak of. The elders revealed the truth, and the two brothers resolutely sold their beloved luxury cars, gathered a million in cash, and rushed through the night to the hospital to save her. After Shen Xiulan recovered, Lin Dashan started live streaming to help agriculture, overcoming heavy difficulties such as raw material shortages and malicious suppression by competitors, and led the entire village in establishing a cooperative to develop deep processing.
