Speaking for the deceased and uncovering the truth behind death, forensic medicine utilizes its benevolence to make greater contributions to the people while safeguarding the rights of the living. Because they understand the relationship between life and death, they can face death calmly and embrace life. According to Professor Liang Liu, the forensic medicine's warmth is reflected in the temperature of life that emerges from the frigid dead. Liang Liu is a renowned expert in forensic science and a mentor on the variety show Workplace Newcomers-Forensic Season. In COVID-19, he and his team carried out the world's first autopsy on the remains of a deceased patient with COVID-19, contributing a fruitful theoretical basis for clinical diagnosis and treatment as well as epidemic prevention and control.
