"I believe the vivid characters and their true-to-life emotions can touch the audience. We want to show young people who can bravely shoulder their responsibilities when they are needed, and their vivid personalities when they are off duty," she adds.

The crew members prepared for four years to make this series. In order to show the professionalism in the work of doctors and police force, they conducted interviews and research at the Affiliated Brain Hospital of Nanjing Medical University, Beijing Tiantan Hospital that is part of the Capital Medical University and Beijing Shijitan Hospital, an affiliate of the Capital Medical University to collect information such as medical cases, doctors' daily life and ideas, and infused the information into their creation.

"For example, in the drama, a neurosurgery expert says neurosurgery operations require precision, so doctors must keep their hands steady. The line comes from the reflection of a real neurosurgery expert collected in our research," says Fang.
