This book is a memoir about US President Hoover, written by President Hoover himself. In the book, Hoover recalled his early career as a mining engineer and his experience of being sent to "work" in the Kailuan Coal Mine in Tangshan, Hebei, China. At the same time, he also reviewed the relief operations he participated in for European refugees and children during and after World War I, as well as the various problems he encountered. As president, Hoover participated in the decision-making of many political and historical events throughout his life. In the book, he also mentioned the beginning and end of the signing of the "Contract of Versailles" in 1919, as well as his role in it, telling readers a true "Contract of Versailles" in his eyes. Through his review of his early experiences, we will see a flesh-and-blood Mr. Hoover, and this book will also restore to us a more real and natural President Hoover.
