Its main locations are in the districts of Jinshan, Songjiang and Wujiang.
The Fengjing is classified as a type of Taihu pig which all occur in the narrow region of mild sub-tropical climate around the Lake Tai region.
The Fengjing has very high rates of breeding, producing two litters per year of an average 12 piglets at first parity rising to 17 piglets at third parity with 12 surviving to be weaned.
The pig grows relatively slowly and has a good, succulent, taste.
