Stories of ordinary heroes

They also lived on a police training base in Nanjing and interviewed many officers about the cases they participated in and their daily life. "Many cases shown in the series are adapted from true cases the police told us about," says Fang.

The drama shows the story of earthquake relief efforts from police and doctors, which refers to the true story in the devastating earthquake which hit Wenchuan county, Southwest China's Sichuan province in 2008. Crew members interviewed some police officers who took part in the relief efforts and got to know many details about their work. Then they shot part of the story in the 2008 earthquake site of Beichuan Qiang autonomous county, one of the worst-hit areas near the epicenter.

"I remember when we arrived at the site for the first day, all of the cast and crew presented flowers to the monument marking the Wenchuan earthquake. We saw the ruins, read the introductions, and many of us cried," says Zhang Tong, director of the series.

"Since I come from Chengdu, the provincial city of Sichuan, I could keenly feel the pain from the earthquake. But people's joint efforts at that time also made me feel grateful. So when I shot this part of story, I put many of my true emotions in the creation," Zhang adds.

According to Zhang, the shooting of the drama ended just several days before the outbreak of COVID-19. Then when he saw the news about the efforts of medical workers and police in fighting the outbreak, he thought of his original aspiration to make this work.

"We want to show two young people, who can shoulder their responsibilities at work, and also enjoy life. It can be seen as a portraiture of many young people in the modern society," says Zhang.
