Actually, there is no fixed style. There are a group of people from morning to afternoon, and a group of people from afternoon to night. If there is breakfast, the time may be from 5: 11 to 11: 11, and the two groups of people will be divided equally. Generally speaking, the rest time is one day a week, but there is no rest on Saturday and Sunday, which is more than two days. At other times, you can take any day off, but some may not be realized.
