Haining is an industrial city in Zhejiang Province in China. It is known for its many home textiles factories. Daireaux immerses us in the heart of some of these factories. It starts with a workers back whose job is to scrutinize miles of tissues to detect any manufacturing defect. The body of the young woman oscillates in an endless goes and comes right-left in front of the tissue which does not stop it falling and becomes thereby curtain. A daylight, which snatches and keeps at a distance at the same time, irradiates the face which we shall never see or with so few details as the recognition is not possible. Then faces of workers appear surreptitiously and disappear behind the oscillation and the endless scrolling of tissues. They are faces closed, tired by the repetition of gestures and the hardness of the work.
