刘永刚

Liu Yonggang is a Chinese author whose works span a notably wide range of subjects; public information about him is limited and his biographical details remain unclear. Judging from the six titles in the collection, his writing covers documentary literature, world history, computer and industrial technology, and personal finance: these include World War II documentary and translated works such as The Last 100 Days: The Tumultuous and Controversial Story of the Final Days of Nazi Germany's Third Reich and the three-volume John Toland decryption set on Hitler, computer technology books such as Fundamentals and Key Technologies of Cybersecurity Emergency Response and The Technical Principle and Data Recovery of Solid-State Storage, an industrial technology work on energy management and optimization control for new energy vehicles, and a finance textbook, Insurance Studies (2nd Edition). This cross-disciplinary range suggests he may work both as a history translator and a technical writer, though his specific roles and background cannot be confirmed; readers should judge his contribution in light of each book's content.
