Potato soap helps hygiene and financial health

CHENGDU－Adding olive oil and alkali to mashed potatoes, Peng Yang stirs the mixture and pours it into a mold. Two days later, light yellow potato soap bars take shape under the sun.

It's not a studio in an urban area, nor a gift-making factory at a tourist site. Instead, the soap-making takes place in the kitchen of a school in Gujue village, Liangshan Yi autonomous prefecture in Sichuan province.

Peng hopes to turn the potato soap bars into a viable business for locals while helping promote good hygiene.
