the most important thing is to know all kinds of management systems and methods, understand the background of various systems, and thoroughly study the suitable conditions for various systems, without preconceptions. The management method must be suitable for the hotel environment, because the environment of each hotel is different, so it is impossible to have a management system that can be applied to each hotel. Even within the same hotel, employees in different departments sometimes have to adopt different management methods. The management system is also time-sensitive. The situation of hotel accommodation often changes with time, and the management system and methods must change with time, place and person.
