Hello, landlord, I also make potato flour. I was going to add my brother and sister's potato powder. Later, I searched some information about potato flour on the Internet and found a pot of fresh potatoes in Shijiazhuang. Later, I contacted several times to study. It tastes good. Now I have opened a shop with many repeat customers. I'm too busy alone. If you want to learn, Baidu should find a pot of fresh potato powder in Shijiazhuang.
