When I was in primary school, I would bring some rice from home to school every day. Because it was very troublesome to bring food at that time, my parents steamed some steamed buns for themselves every day, and brought them to school every day for me to eat for a week. At that time, I felt particularly uncomfortable, but I could only endure this kind of pain in order not to starve to death, so I think steamed bread can make me eat for several days.
