Problems solved by technology

In addition, the current yam products mainly appear in the form of a single raw material, which cannot fully meet people's dietary health needs.
There are relatively many jujube products, but they mainly appear in the form of a single raw material, and there are few products that are compatible with foods that also have health benefits such as yam
Modern people have a fast pace of life, increased pressure in life, and pay more attention to health care, but they don't have much free time to formulate food according to their needs
