Nutritional pig is a pig-raising mode packaged on the Internet, but due to its imperfect management system, it is difficult to guarantee the personal interests of users without relevant laws and regulations when it comes to the health and safety of pigs.

"Yunyang" refers to a mode of raising pigs. The public subscribed for piglets, and the cooperative not only helped raise and slaughter them, but also delivered them to the door, which was welcomed by everyone.
