This Is ****

This book is written in a simple and easy-to-understand style, with smooth writing and explains sociological concepts in layman's language. There is a sentence in the book that I like very much: "The purpose of social interaction is equivalent exchange." This sentence points out the essence of social relationships. This book can help us avoid ineffective social interactions and improve work efficiency. It is worth reading.

A book like a dictionary only touches upon many characters and ideas. Some parts are concise and easy to understand, while other parts are more difficult to understand.
