But for some, who have done the same job all their lives, work seems to have a more profound meaning. Symphony conductor Zheng Xiaoying hasn't stepped back from her career even at 93, and received the invitation to conduct a chorus at a conference in July last year. The fourth episode recounts how she prepared for and accomplished the task.

"In the early stage of a career, people often rush to achieve something. But, in the latter stages, the desire often changes to belief, which contains complicated emotions, and not only about love for the job, or a wish to realize a dream. Behind all the struggles and hardships shine human qualities," says Qin.

The production team carefully selected the jobs depicted in the series. It also features new and lesser-known jobs, like test pilots of prototype aircraft, people who provide attendant services for hospital out-patient visits and those who protect wild animals.

"The appearance of these new jobs reflects market demand and the changing of the times. They present new opportunities for individuals to realize their dreams, while creating social value for people who strive for a better life," says Zhou Quan, deputy director of the documentary center of Shanghai Media Group.
