In the 23rd year of Kaiyuan, outside the city of Chang'an, among the ruined temples and cold grass, Lin Wei, a third-year student of modern clinical medicine, woke up from a biting cold wind - the moment her fingertips touched a copper pharmaceutical pot from the Tang Dynasty, she actually traveled from the medical school's ancient book library to the prosperous Tang Dynasty. She had nothing but a first-aid kit hidden in her waist and a head full of modern medical knowledge. Facing the damp and musty ruined temple, the washed-white coarse cloth skirt, and the plight of the "abandoned children in the righteous village" among the people, she was full of panic and helplessness when she first arrived.
By chance, she met Chuntao, an orphan girl who was seeking medical treatment for her younger brother. She found that six-year-old Xiaobao was suffering from acute pneumonia and dehydration, but the local doctor only concluded that he was "possessed by evil spirits". Lin Wei suppressed the shock of traveling through time. He relied on the antipyretics in the first aid kit to accurately control the temperature, used a stethoscope to judge lung signs, and went up the mountain to collect dandelions, honeysuckle and other herbal medicines to combine them. Using modern medical thinking combined with ancient methods, he actually saved the endangered Xiaobao.
Her medical skills were beginning to show off, but they also aroused doubts and difficulties from the old doctors in the shop, which made her see clearly the backwardness of folk medicine in the prosperous Tang Dynasty: people were timid about doctors because of poverty, minor illnesses became serious, and folk remedies cost lives. From surviving in a ruined temple to temporarily renting a small courtyard, from recuperating Xiaobao to helping neighbors treat diarrhea, Lin Wei gradually faded away from the initial fear, using the kindness of doctors as a light to find a way to gain a foothold in the unfamiliar land of the prosperous Tang Dynasty. She not only needs to rely on modern medical knowledge to solve each disease problem, but also needs to open up a medical path for herself and more suffering people under the shackles of the rule of "practicing medicine without medical qualifications". In the morning light of Chang'an, the story of her medicinal fragrance has just begun.
