At the dawn of China's Reform and Opening-Up in 1979, Du Heng, a revered master of traditional Chinese medicine, unexpectedly finds his soul transported into the body of Lin Yanzhou, a notorious good-for-nothing and spendthrift from Hongqi Commune. Just after his rebirth, his predecessor's father suffers a life-threatening heart attack brought on by extreme anger. Western medicine proves helpless, while his family and neighbors blame and despise him. Using the long-lost ancient acupuncture technique known as the Hungry Horse Shaking Bell, he saves his father with just eight needles and begins to change everyone's opinion of him. From then on, he turns over a new leaf, takes over the Lin family's clinic, and dedicates himself to treating patients, making amends for his past mistakes, and restoring family bonds. Repeatedly facing challenges and competitions from skeptics of Western medicine, he demonstrates the profound foundations of traditional Chinese medicine through clashes between Eastern and Western medical practices. As he protects his family and passes down ancient healing techniques, he writes a legendary rural tale of redemption through rebirth and the preservation of China's traditional medical heritage.
