Ice powder made by hand by traditional plants seems to be rare.
The traditional ice powder is brown sugar water boiled with local brown sugar, but now people add more accessories to the ice powder: peanuts, red beans, mung beans, hawthorn, taro balls, Noemie balls, fermented grains, various flower sauces and so on. It is also to introduce dessert ice powder that meets the tastes of young people. Traditional things are always enduring, and those who create them will only give them more new definitions to make them more in line with people's taste changes, so that they will be passed down all the time.
