The documentary, aired on the streaming platform Bilibili since early March, has notched up more than 7 million views so far.

"I wanted to capture and present to the public the charisma of talented children in a certain field," says Sun Chao, the documentary's director, adding that many people fail to find a life passion throughout their whole lives and it's good for children to find that at a young age.

They should be encouraged to chase after what they want, she says.

"I hope the documentary will inspire parents to be more willing to support their children's interests and hobbies."

The series also follows 9-year-old Wu Gangyun's continuous efforts to improve her dancing skills for more than a year.

The girl grows up in a remote village in Yanshan county in Wenshan autonomous prefecture, Yunnan province.

Her father is a truck driver and her mother runs a food stall where she usually hangs around to help and practice her dancing skills by getting online video tutorials.
