There should be no loss, but the most important thing is that it is cheap and delicious. Generally, there are many take-away shops at the entrance of universities, and there are snacks in junior and senior high schools, such as tenderloin, stinky tofu and barbecue, which can be bought after school. It is best for universities to have takeout, large quantities and the like. That kind of bibimbap was my favorite in college. You can try.
