Very early every morning, Mr Zhang Heshan proudly walks the section of the Great Wall of China that he has taken care of for the last 40 years. He picks up litter and checks if repairs need to be made. His wife Wang Yuexia, and friends thought he was crazy, but he realised the importance of preserving cultural identity, long before any one else.

He has worn out 200 pairs of shoes doing this work.

This Shaman in Lugu Lake creates impressions of demons from the underworld out of flour and water in order to bring them forth and then banish them for good.

He coughs and rocks and sways as he works, and reads prayers in a smoky voice, raspy with the legacy of a lifetime of cigarettes.

He sacrifices a chicken to bring about the healing, and we tentatively eat it in a soup made from lake water.

A Mosuo woman walks two hours each way to the market in order to sell dried rose petals for tea to support her children to go to school.

She smokes a pipe while dressed in full traditional dress, and laughs in surprise and aquiescence as we ask to take her picture.

A Mosuo grandmother stands in the courtyard of her mountain home, drying corn after the harvest. This corn will be used for the next year to eat and trade within the village, to support the family.
