First of all, make clear the characteristics of nipples, which young people prefer. There is a strong milkshake (banana, chocolate, vanilla) flavor, fashionable and romantic (packaging and advertising words can be reflected). Second, find the right customers. For example, if you see a customer who is choosing milk in the supermarket, introduce him, especially those who buy yogurt and juice. Third, give it to children, and children will clamor for it if they like it. Fourth, ask the company for some gifts and buy them together. The effect is also remarkable. The above hope can help you.
