Opening a restaurant often requires at least three people, a kitchen, a front desk and a waiter.

If you want to run your own business, you can consider a restaurant in the form of a stall, that is, items that don't need to be served in class and don't need to be supplied immediately.

It is best to make products in advance, which can be kept for a period of time, and customers can take them away when they buy them.

Products can be made in advance or stored, sold when they are busy, and made in their spare time.

For example, Cao Zhuangyuan's biscuits can be delivered in the freezer by cold chain, made on demand, or one hour in advance when busy, as long as there is a special person at the cashier.
