Do you have to cook it before eating it, then peel it and soak it in water for one night? Do you still feel a little astringent if you can't eat it? If it is true, then this bean is called jujube bean (Hakka). I come from the ancient town of Luodai, so there are many kinds at home. Every time you eat, you boil a big pot, and then the whole family peels it together, so you can eat it for several days! Hehe ... It's still very expensive in the market. 4.5 yuan or 5 yuan is a kilo, is that right?
