During the Spring and Autumn Period, Ji Ran, an expert in Vietnamese business, put forward a famous business saying: "Drought means boats, while water means cars". This means that when the weather is dry, although the rivers are cut off, don't rush into the car business. On the contrary, we should invest in the purchase and construction of boats, because "a long drought brings rain", and boats were naturally in demand at that time. Similarly, when the flood comes, there is no need to rush to do shipping business, but should invest in the operation of cars.

Reflect? Are commodity value and use value the unity of opposites? This economic principle. Therefore, in the daily application of Chinese medicine products, don't follow the trend. For example, if Cordyceps is expensive, I will plant Cordyceps, and if Platycodon is expensive, I will plant Platycodon. We should carefully grasp the market trend and always stay ahead of others.
