Spring Is Deep in Chang'an, and the Heart of Medicine Is Blooming

Lin Wei, a modern medical student, accidentally encounters a reagent accident in the laboratory. When she opens her eyes, she travels to Chang'an in the prosperous Tang Dynasty and becomes "Lin Wei", the daughter of an official family. Entering a strange era for the first time, she not only had to adapt to the ancient etiquette of life, but also faced the conspiracy behind the original owner's "accidental" fall into the pool. She also had to struggle to gain a foothold in the Tang Dynasty, which lacked medical treatment and medicine as a frail girl.​ Relying on modern medical knowledge, Lin Wei saved Mrs. Zhang who suffered a stroke at a critical moment. She broke through the limitations of traditional medical skills with unique first aid methods and conditioning ideas, and showed her first talent. She refused gifts from wealthy families and donated her property to poor people. Her kindness and talent not only won the respect of her neighbors, but also unexpectedly attracted the attention of King Wu Li Ke, who saved the original owner.​ King Wu Li Ke, the son of Emperor Taizong of the Tang Dynasty, was talented but was trapped in the court whirlpool due to his life experience. He was attracted by Lin Wei's unique conversation, superb medical skills, and thoughts that transcended the times. From their initial gratitude and curiosity, the two gradually developed a symbiotic relationship with each other from time to time. However, the undercurrent of the palace struggle is turbulent, and the truth about the original owner's fall into the pool gradually emerges. Lin Wei's modern medical knowledge not only brings her opportunities, but also involves her in a deeper crisis - some people covet her medical skills, some are afraid of her relationship with the King of Wu, and there are even more unknown dangers lurking in the dark.​
