10 years ago, my father-in-law bought a set and spent less than 8000 yuan. 1 There are three covered pots, two of which are all-purpose covered (pressurized) soup pots and one is a frying pan. Comments: Advantages: energy saving, fuel saving, less oil fume, different cooking methods, lazy cooking methods and gland are all very easy to use. Five points. Disadvantages: it is more troublesome to clean every time, but it is okay not to clean, and lazy people don't wash. It's a little expensive and heavy.
