Jiuzhai pig bristle is mainly grown in the alpine shaded area with an altitude of 2000-2900 meters. The growing soil is mainly mountain humus, with high organic matter content, low temperature and large temperature difference between day and night, so that honey fungus has sufficient time to absorb the host trees. Nutrition develops. Product characteristics The wild products of Jiuzhai piglets are mostly round, with large individuals and low density.
