The "circle given by merchants" is not used to raise the water level, but to suppress medicinal materials, such as flowers, leaves and whole grass, so that they sink when frying.

There are few Chinese medicines to be decocted, and the water consumption is difficult to control. There are two solutions:

1. decoct the two drugs together, divide them into 4 parts and drink them in two days;

2. Water frying-doesn't the decocting pot have a ceramic bowl? First add water to the pot (3-5cm above the safety line at the bottom of the pot), put the medicinal materials in a bowl and soak them in cold water for half an hour, then put them in the pot, cover the pot and fry until cooked.

It should be noted that the decocting method of dividing water is slightly longer than that of adding water directly, and it needs to be decocted twice. Of course, the second frying can use hot water, which is about 2/3 shorter than the first frying.
