The writing style of this book is concise and clear, explaining the currency code for us in easy-to-understand language. The content starts from the era when there was no currency in primitive society, and gradually reveals the origin and development of currency, allowing me to understand the close connection between currency and human development. Moreover, some of the questions in the book are also very interesting, such as how people traded in an era without currency, which triggered my thinking. All in all, this is a book worth reading.
