Why is the essence of the queen bee of Beijing Double Crane missing?

This situation is due to changes in market demand and rising production costs.

1. Changes in market demand: With the increase of consumers' demand for healthy food, more new healthy foods are constantly emerging, while the traditional queen bee essence has a slow effect and low fit with modern health concepts, which leads to a decline in market demand and eventually stops production.

2. Rising production cost: The production process of queen bee essence is complex and costly, including bee breeding, queen bee extraction, semen extraction and other links, which makes many manufacturers choose to give up production or raise prices, resulting in reduced market supply.
