The canteen for 500 people is very big. If 500 people eat here, then you need more than 10 people. Because of the different division of labor, it is impossible for one person to finish a job with two or three people. Therefore, the selection of candidates must be just right, otherwise it is impossible to accomplish so much and the workload is so great.

Moreover, we must find more mature employees to work for this canteen. If you find some novices, it's easy to be in a hurry. Therefore, we must be prepared, train personnel, understand our own abilities, and book purchases. We should know how many things we have, but we shouldn't waste them. If we don't hurry, we can't finish such a large quantity.
