Open a grain and oil store to make money? This question depends on your business situation. If you manage well, you will definitely make money. Now everyone talks about keeping in good health and selling more whole grains, and business will be good. We have a native of Henan who has been selling grain since 2000. In recent years, the scale has been considerable, and there are twenty or thirty kinds of whole grains alone. I wish you a prosperous business here.
