How many times do you need to get up in the morning to set up a stall to sell rice rolls? Do you need to prepare anything?

Look at when your school opens. Ask any elementary school student near you, and ask them how long their school hours are, usually at 6 o'clock. Then add the time you have to get ready for rice rolls, and it will take you almost an hour to get ready, which means you will get up at 5 o'clock and start getting ready. Then at 5: 45, it will be pulled to the gate of a nearby primary school to wait for the primary school students to go to school for breakfast. When all the primary school students have gone to school, if there is any left, it will be pulled to the gates of some large factories and small factories, basically at 7: 3, and workers from those large and small factories will be waiting for the factory to open.
