What is the book Six Towers about?

Tamia Liu's Old Topics was written by Zhou. Lu Shang was Jiang Ziya, a strategist in the Western Zhou Dynasty. His title is obviously an excuse, and its real author cannot be examined in detail. Liu Tao wrote a book at the end of the Warring States Period. People used to doubt this, but bamboo slips Tamia Liu and Taigong were unearthed from the Han Tomb in Yinqueshan in 1972, which confirmed that this book was indeed a pre-Qin war book. The earliest existing version of Tamia Liu is Seven Books of Jason Wu in the Southern Song Dynasty, with 6 volumes, 60 articles and 23,000 words. Six Roads summarizes the essence of pre-Qin military strategists and philosophers. Through the dialogue between Zhou Wenwang, Zhou Wuwang and Jiang Taigong, it discusses and expounds the theories, principles and methods of governing the country, the army and directing the war. The first two volumes, Wen Tao and Wu Tao, focus on strategic issues, while the last four volumes, Long Tao, Tiger Towers, Leopard Towers and Dog Towers, focus on how to run the army and guide operations. Liu Tao is a masterpiece in the pre-Qin art of war, which is often unprecedented in political and military theory. It preserves a wealth of ancient military historical materials, such as compilation, weapons and communication methods, and has important theoretical and historical value.
