I am on the way to interview a potential participant, currently going through a small local market, here they sell fresh vegetables, fruits, pork and live poultry on both sides of the street. Live chickens, ducks and geese are mixed and kept in cages, I can smell the faeces. A vendor (female) is slaughtering a chicken for her customer who just selected one from the cage, she seems very proficient, only wears an apron but no gloves, the ground is covered by blood and feathers. Not far away, there is a woman wearing an orange uniform who is cleaning the street. After 5 minutes, I turn my way into a cropland, surrounded by Karst mountains, there are mostly rice and some vegetables planted, small birds are flying, two cattle are eating grass. I see a house across the cropland, which is the home of our potential participant, I hear a dog barking when I approach the house (observation made in Xiaolou County, Guangzhou, Guangdong province, 25 September 2015).
