The word "Public Relations" comes from English public relations. Publicity means openness, openness and openness, and relationship means relationship. Together, these two words mean "public relations" in Chinese, sometimes called "public relations". Since the birth of public relations, people's efforts to give it an accurate definition have never stopped. Because everyone has different understanding angles and different understanding of the connotation of public-private relationship, many definitions of public-private relationship have been formed. In the mid-1970s, Dr. Rex Harlow, a famous American public relations scholar, collected 47 definitions of public relations. Others say that there are thousands of definitions of public relations. Therefore, some people say humorously that there are as many public relations scholars as there are.
