Zhengzhou, Henan. Potatoes can be said to be the most amazing food on earth. Whether it is boiled, fried, fried, shredded, main ingredients or side dishes, all are delicious. Slicing and frying, it has also become a lever in the snack industry. A potato chip a day makes people go further and further on the road to a fat house. Even people who eat all the delicious food in the office can't resist the temptation from potato chips. "If the end of the world comes, please make sure I eat the last bag of potato chips!" I always thought that I couldn't live without potato chips, and I wasn't crazy without them until we met it-a yam chip more magical than potato chips! Moreover, yam has the same origin of medicine and food, and has the functions of invigorating spleen and stomach, promoting fluid production and benefiting lung, tonifying kidney and astringent essence that potatoes do not have.
