With the expansion of the production and circulation scale of agricultural products, in addition to wheat, corn, rice and other cereals, cash crops such as cotton, coffee, sugar, livestock products such as pigs and live cattle, and forest products such as wood and natural rubber are also listed and traded in the futures market.
