Wuzhen: Old Pharmacy.

The raw material for dye printing is Eupatorium fortunei, a herb that turns into indigo after being fermented and precipitated. For convenience in transporting the cloth, the weaving workshops and dyeing workshops are usually on the same street, only a few doors from each other. At the dyeing workshop, the cloth is soaked and air-dried again and again to produce white flowers on a blue background. (shanghaifinance.com)
