Delivery activities, such as grouping, a department, is to give everyone an order, and then one person needs to limit the number of pages after reading a book, for example, one person passes it to the next person within one week or three days. I think few people will be ashamed of delaying the next person's time. Finally, whoever is stuck in punishment must be severely punished in order to make people really do it. Many times, it is good to be forced out.
