Just like when my girlfriend and I were in different places, we often expressed our longing for each other through letters, which gave me a deeper understanding of the development of the postal industry. And I think the author must be a knowledgeable person to put so much knowledge into this book. I want to recommend this book to my friends so that they can also learn so much interesting knowledge!
