It is in March that work begins on the fields in the terraces of red earth in Dongchuan in the province of Yunnan in the southwest of China.

Here very little mechanization considering the slope and the narrowness of the grounds.

Everything is done with animals or by hand of man and woman.

Fertilization is still ensured by manure, transported in bags and placed in each planting hole of potato or corn, which, to accelerate the growth of plants and fight against the harsh climate of these terraces located at 2000m d altitude is covered with plastic film.
