A worker takes fresh Parmesan cheese off the storehouse (储藏室) shelf in a dairy firm (乳品公司) in Modena, Italy. In times of economic difficulty, it is hard for small Italian businesses to get long-term loans from banks. This dairy firm is an exception because of its novel idea: issuing bonds (债券) guaranteed by cheese. Parmesan cheese is a hard one that is considered to be among the top cheeses.
