Yes, some kindergartens are like this. In some kindergartens, steamed bread in their canteens, like this breakfast, will be delivered by some contracted food companies outside, and then some older kindergartens, if they have their own independent canteen kitchens. He will make fresh steamed buns at school to prepare breakfast.

So it can be said that most of the buns in canteens and kindergartens are take-away.

Because most kindergartens don't have a good kitchen to prepare breakfast, it is also a common way to distribute steamed bread, so the final conclusion is that most kindergartens distribute steamed bread.
