5. Some people are used to adding a handful of japonica rice when cooking barley and red bean porridge, thinking that it looks sticky and tastes more delicious. In fact, this is not the case.

Because the functions of red beans and barley are to remove moisture, while rice is a crop that contains moisture, which directly offsets the dehumidification effect of this porridge.
