Working for themselves

As a result, crew members issued 1.8 million online questionnaires to gauge people's job satisfaction, and retrieved about 2,000 effective answers. They communicated with those people over the phone for a month, and tried to choose some who gave the impression that they "really enjoy working". On that basis, they finally chose six people from different industries and places, whose stories are featured in the series.

The second episode features Tang Hengxin, a 57-year-old engineer who works at a drone company founded by 22-year-old Li Kunhuang. They try to develop a drone system which can help extinguish forest fires, reducing the need to put actual firefighters in harm's way.

"Conflicts happen due to generation gaps. They have different ways of communicating with people. For example, Li, a young man, tends to be straightforward at pointing out others' mistakes, while Tang Hengxin prefers to be less direct. But, with a common goal, they can come together to try and create something," says Hu Yixin, director of the second episode.
