Problems solved by technology

In addition, the cherry skin is thin, and the pores of the fruit skin are also large.

Usually, the products sold during the Spring Festival are made from a large number of freshly stored cherries. After the rotten and wrinkled fruits are selected, the better quality ones are selected for sale, which is also one of the main reasons for the price increase.
