Regardless of the school, in my opinion, Guo's communication course is the most popular communication theory, and two of the three universities have designated this course. This book is really good. I suggest that you can buy this book whether it is in the bibliography or not.
In addition, the postgraduate entrance examination for communication generally involves journalism theory, advertising, public relations and New Biography at home and abroad.
Take Hunan University as an example: Communication needs at least five reference books, namely Journalism Theory (Wu Gaofu, the principle of journalism), Communication Theory (Guo, the course of communication), Sino-Singapore History (the history of journalism and communication in China), Advertising (the course of advertising) and Media Management (Wu, the course of media management); In addition, if you have enough time, you can also read two reference books prepared by journalism candidates.
