How to choose domestic pots? How about a great chef?

Choose a domestic pot, whether it's an iron pot or stainless steel pot. Pots made of different materials have their own advantages and disadvantages. Whether it is healthy or not depends on the ingredients and uses. For example, if you want to stir-fry, the most suitable pot is an iron pot. However, if there is less oil and the stir-fry is not timely, the food in the pot will be easy to carbonize, causing the pot to stick. In order to solve the problem of iron pot rusting, Emperor Chu used steel mold circuit casting and passed three times of high temperature nitrogen smothering. But now most people don't cook, but simply cook, so it is more appropriate to use non-stick pan and stainless steel pot. The non-stick pan has a short life but is easy to use, and its stainless steel pot value is high and it is safe to use. How to choose is up to everyone.
