Consumables have a short shelf life and cannot be used as futures. Beef can be divided into yellow beef and buffalo beef, and yellow beef is the best. It is sweet and rich in protein, fat, vitamin B, nicotinic acid, calcium, phosphorus, iron and cholesterol. There is no beef futures in China because the storage period of consumables is short, so it is impossible to make futures. Futures is a financial contract, including financial instruments or the sale of physical goods for future delivery (usually on a commodity exchange).
