Doing business, I think, is nothing more than knowing what the other party wants, knowing what they want, then knowing what the operating rules of their own company and customers are, and finally meeting their needs by possible means while achieving their own goals. What the other party wants: The other party may be a dealer, distributor, terminal point of sale or consumer. They all have different needs. In addition to consumers, others may need sales, profits, expenses, inventory control, personnel support and so on. First of all, we should understand each other's interests, and then try to combine their interests more closely. For example, if the customer says that the inventory is high now, then we should provide the solution to digest the inventory and suggestions for safe inventory, instead of simply not ordering. What you want, this is also very important. To put it simply, you should have principles, not simple ones, but better ones. For example, as we all know, the cost, price and gift investment are simple and effective, but sometimes they are higher. The rules are hard to say. Every company is different. Ask a colleague if you don't know. Finally, FMCG is very simple. You can't learn without any knowledge. The key is to work hard and not to set an upper limit for yourself easily.
