When selling snacks next to kindergartens and primary schools, you should generally choose snacks with bright colors and good taste. In kindergarten, candied haws, quail eggs and zongzi are all suitable. In kindergartens, there is no consumption level, and parents or grandparents pay the fees. Generally, you will choose some healthy snacks, but in primary school, you can choose some snacks with good taste and low consumption, such as baked gluten, iron plate, squid and biscuits.
