Ethnic groups in focus

Although the three Chinese team members were contributing to the project for free, Adolf still has to bear other costs of making the documentary.

"We could see he is just following where his interest takes him, without considering any future returns," Dong says.

To date, Adolf and his team have stayed in Guizhou for two months and are full of enthusiasm and motivation as they have found a trove of interesting things to shoot while exploring different village lifestyles.

Afterward, they plan to move on to Hainan and Yunnan provinces to record the myriad ethnic groups based there.

"It is just the beginning of our documentary journey and I'm looking forward to visiting all the other places," Adolf says.
