"Specialty" refers to a specialized occupation, which requires a high degree of knowledge and ability in academic or technical aspects. Whenever encountering problems in this area, professionals can usually give reasonable answers, which most people can't do because they don't have relevant training.
The moral values and codes of conduct formulated by professional ethics groups according to their professional characteristics are ideal guides for working in this field and provide basis for professionals to make correct choices when encountering professional ethics problems.
How to manage the application of these knowledge and abilities and promote better service to the public can be regarded as a moral topic, also known as professional ethics. According to the different characteristics of each major, special professional ethics will be established in its field, such as medical ethics, business ethics, legal ethics, engineering ethics and so on.
Only professionals who are familiar with professional ethics can make correct judgments, apply the skills they have mastered, seek truth from facts and do not speculate. It is difficult for people who have not received relevant training to do so. One of the earliest examples of professional ethics should undoubtedly belong to the Hippocratic oath. Today, doctors still swear to keep some revised Hippocratic oaths.
