If you purchase original rice, there is no need to process it. Do you want to open a rice factory or be a rice wholesaler? To open a rice factory, you must have a good supply of rice, learn to identify the variety and quality of rice, and have smooth rice sales. If you want to purchase rice for processing, you must have a processing site, a raw grain warehouse, a finished product warehouse, and a rice and rice inspection room. If you want to be a rice seller, I suggest you start from a small shop. Take it step by step. You see your friend making money, ask him how many years he has been doing it.
