It's the kind with a steamer in Yitian, which is very easy to use. A large-capacity steamer can supply our family of six. Besides steaming steamed bread and rolls, I also like to use it to steam fish and stew eggs, which is particularly practical. It's the lower row that sucks the soot. Every time I finish cooking, there will be no smell of oil smoke in the kitchen. It doesn't matter if you don't clean the kitchen for a month. Of course, don't do it for so long.
