Which discipline does interpersonal communication belong to, and what books are there about it?

From a professional point of view, it is a kind of sociology. But if you really want to learn interpersonal relationships, it also involves psychology and logic.

There are many books in this field, but only those books with novel ideas are copies. I think people who learn interpersonal relationships well and want to apply them in practice should find the essence of books, write them on paper and read them ten times a day. (Read a book and summarize five articles by yourself, no more than ten. ) Here I recommend two:

1. If you want to deal with the interpersonal relationship of China people, you should read Ceng Shiqiang's books or CDs to survive in the complicated thinking of China. He incisively analyzed China's interpersonal relationship.

2. Books that want to make yourself harmonious in all aspects, happy in your family and improve your positive attitude (which is also very practical for salespeople) should be the strengths and weaknesses of human nature.
