Grain flour is not a medicine, so there is no special restriction. Generally, it is eaten in the morning and evening, about three spoonfuls at a time, because the flour is original, there is no added essence, only natural five-grain essence, and because the five-grain flour is ground into powder, its solubility is not as good as milk tea and other additives, that is, washing powder. You should soak in hot water for two or three minutes first, and you can add condensed milk and honey or sugar, salt and fresh milk according to your own preferences, which will be more delicious. I hope it helps.
