Is it true what The History of the Eastern Zhou Dynasty tells?

Biography of the Eastern Zhou Dynasty is a historical story from the end of the Western Zhou Dynasty (789 BC) to the unification of the six countries in the Qin Dynasty (22 BC1year), including the Spring and Autumn Period and the Warring States Period for more than 500 years. The content is quite rich and complicated. The history described in the History of the Eastern Zhou Dynasty is just such an era, and all the stories are unfolded under such a big background. The facts described in it are based on four historical books: Warring States Policy, Zuo Zhuan, Guoyu and Historical Records, and the scattered historical stories and biographies are arranged in chronological order and merged into a furnace to become a historical romance with complete structure. Before the Qin and Han Dynasties, some historians described and evaluated historical events from a principled standpoint, and sometimes their meanings were hidden in recorded words, which was difficult for people without certain knowledge to find, let alone understand. The popularity of this book is to make the words like a reef clear, and it is clear to everyone at a glance that all kinds of right and wrong, good and evil, faithfulness and treacherous wisdom are exposed in broad daylight. This is the author's intention to write this book and their contribution to future generations.
