Lin Wei, a modern medical student, travels to Chang'an in the fifteenth year of Zhenguan in an accident. The first aid kit she carries with her becomes her only reliance in this era. When an epidemic broke out in Zezhou, people in Chang'an were panicked. She relied on modern medical knowledge to survive in an era when surgery was considered taboo and medical standards were backward. When she used boiled linen to treat wounds and used isolation to prevent and control the epidemic, she not only aroused doubts from traditional doctors, but also attracted the attention of Li Jingyuan, a descendant of a family who was suffering from a strange disease. One is a time traveler with modern first aid knowledge, and the other is a noble man who is deeply influenced by traditional medicine but curious. The two met in Chang'an City where the plague was spreading. In the collision between medical theory and modern medicine in "A Thousand Gold Prescriptions", under the supervision of the palace female doctor and the mysterious intervention of the Hu doctors, they jointly faced the threat of disease and the constraints of ethics, and a love that spanned time and space quietly grew. When Lin Wei's scalpel cuts through the prejudices of the times, and when Li Jingyuan's trust breaks through class barriers, can they write a legend about redemption and love in this prosperous Tang Dynasty?
