Bean one. The bean 1 contract is domestic food-grade soybean, and the price of soybean in farmers' hands is the same as that of bean 1, because the bean 2 contract can be delivered globally. From the price market, the futures price of Bean 2 is lower than that of Bean 1, because the delivery range of Bean 2 includes genetically modified soybeans and non-genetically modified soybeans, mainly for oil extraction, but the delivery product of Bean 1 is the current soybean standard and the price is higher.
