"Moreover, since China implemented the third-child family planning policy, pediatricians are becoming a focus. Whether there are enough pediatricians to protect the health of those additional children has become an important question and a source of people's peace of mind and social stability. So it's time to pay attention to them."

The production records events that take place in Hunan Children's Hospital, a large children's hospital in Central China's Hunan province which deals with at least 8,000 patients each day. Crew members set hidden cameras to capture footage in carefully selected departments of the hospital 24 hours a day without any interference.

"We want to record the true process of doctors' work, from receiving the patients, treatment and hospitalization, through to the recovery and discharge of the patients. During the process, we try to show the interaction between doctors and their patients, breathtaking moments of heroism as doctors save the lives of critically ill patients and impart knowledge that parents should know when raising children," says Wang.

"The production generally reflects our daily work," says Doctor Fan Shuangshi who appears in the documentary and works in the hospital's neurosurgery department.

"Many cases shown in the documentary have a good resolution. After our efforts, the children are saved, though in reality we face more helpless situations when we are unable to save some patients. But generally, it shows our daily work," he adds.

He wanted to take part in the filming because he wants to enhance people's understanding of pediatricians, and spread knowledge that can help those raising children.

"Documentaries record reality. I want people to understand our daily work, so that we can communicate better when they visit the hospital, and the relationships between doctors and patients can also improve.

"Moreover, I hope to explain some facts about children's illnesses, like how strenuous movements while dancing and playing may lead to nerve injury among children who have tethered cord syndrome. People should beware of their children's behavior and recognize early symptoms of illnesses as soon as possible," says Fan.
