The breeding farm has signed a recycling contract with the slaughterhouse, so they all have to return to the slaughterhouse

The hotel purchases its own white strips from its own market, or is provided by a salesperson who specializes in supplying white strips.

As for the hair and offal, you can make a huge profit, and you have signed a contract with the recycling manufacturer. Down jackets, badminton, etc., the offal and hair can be used as feed. Accept me,
