You can use the phone. Go up and have a look when you are free. If you have six people, there are three people in a class, two cooks and a waiter. Then change to those three, and these three go to rest, so you don't have to spend money on food, and you can make money quickly. Of course, if you have time to surf the internet, six people will go to work together. Feed a little occasionally.

It is also a good way to build a trumpet. You can exchange things that are not on the menu, build more trumpets, and the trumpet can also send something to Dai Hao. Pretty fast. That's basically all. Let's summarize the rest of the details ourselves, hehe ~ ~
