of course. Especially at the gate of primary school. When I was in primary school, my classmates opened a canteen in front of the school, and his family earned more than 1 yuan a day. In addition, they also opened a place for students to eat. There are many delicious foods to buy ice cream in summer and sausage in winter, but you have to avoid the canteen that the school opened earlier than you. In case you steal someone's business.
