The re-boiling pot means that the temperature is high and it can be heated all the time, but it should be based on the same principle as the smoldering pot without taking away the heat source, that is, the things in the pot are cooked by the heat preservation effect. I have never used a re-cooking pot, but I have used a smoldering pot. The pot can achieve the effect of stewing food, but the taste is still different from the actual stew with fire. Personally, I think beef bone soup is better cooked. So if the landlord thinks that only stewing is ok, then buy a reputable braised pot.
