When Lin Yi, a Chinese medicine intern, was suppressed by the department and faced dismissal, he realized that the Chinese medical system could see the entries of patients' diseases. He saw through the critical diseases misdiagnosed by his colleagues, saved many critically ill patients by relying on ancient acupuncture and unconventional ancient prescriptions, resolved the slander of traditional Chinese medicine by Internet celebrities, and dealt with difficult and emergencies such as mass poisoning and vegetative state. He became a disciple of the famous Chinese medicine doctor Zhang Qingshan. He resisted the rejection from his peers and insisted on practicing medicine at an affordable price. He used real medical skills to break the prejudice of the supremacy of Western medicine and revive the reputation of Chinese medicine.
