First: supply must be guaranteed. No matter what you want to sell, a good supply is definitely the most important. As far as Wan Wen walnut is concerned, quality, price and quantity are very important. The quality of Wan Wen walnut is closely related to its variety and appearance. Nowadays, more expensive new walnuts can be sold on the market, mostly because they belong to a "niche variety", and those walnuts whose retail price has almost fallen to the bottom are basically due to overcapacity. Supply exceeds demand. Nuclear merchants and nuclear farmers are two concepts, which shows that most nuclear merchants do not own land and walnut trees themselves, which makes the supply of goods more important. Having a stable supplier with reasonable price, whether it's tree packing or wholesale purchasing, can keep your business under your control at any time-in other words, you must have enough reserves to really start, including funds, products, high-quality samples, suppliers, alternative suppliers and sales channels. Remember, there must always be more than one "alternative supplier", so that you can not only worry about the immediate problems, but also have enough room for bargaining.
