Report Summary 1. Report Industry Investment Rating No information provided. 2. Core View of the Report Despite the overall increase in new - grain production, the grain quality in North China and other regions is severely differentiated. The actual supply pressure may be less than last year. The market favors high - quality corn from Northeast China, and many are stocking up there. New - grain sales are fast, and demand is strong. It is recommended that grain - using enterprises purchase at low prices and moderately increase safety reserves, while traders should buy low and sell high [7]. 3.
