Laoma Apple Orchard

A showcase site I built in my spare time for a family orchard in Gaotang, Shandong. Every apple is hand-bagged while still small, and no pesticide is used all season. The site explains the bagging, picking and shipping process — and lets the farmer take orders directly on WeChat.
