"Research" is a systematic inquiry activity, so it must include basic elements such as purpose, process and method. In other words, "research" is an activity with clear plans and intentions, usually aiming at discovering the laws of things, solving practical problems or improving the actual situation.
"Research" has a strict implementation process, which is not arbitrary. It is usually carried out step by step and in stages, with a strict and systematic operating procedure. "Research" is always accompanied by the choice and application of methods. It usually uses specific methods to adjust the development of the whole activity, and the choice and application of methods largely determines the success or failure of research. It can be seen that "research" requires professional knowledge and specific training.
