Ordinary kettles are specially used for boiling water. Limited by its function, it can only boil water and cannot be used for other purposes. Health pot has many functions, such as cooking porridge and soup. Porridge soup can preserve health, which is why it is called health pot instead of porridge pot. I personally have a Qinyuan health pot, but I just bought it. In addition to cooking porridge and soup, I will also use it to make yogurt as afternoon tea, which is really enjoyable.
