Although his life and deeds are limited in the history books, his profound military thinking and excellent strategic planning have had a profound impact on the course of Chinese history. With his unique resourcefulness and precise strategic vision, he laid a solid foundation for Qin Shi Huang to unify the six kingdoms.
Wei Mi, formerly known as Wei Mi, was a native of Wei in the late Warring States period, and was respectfully called "Wei Mizi" because of his deep knowledge of the art of war and his ability to strategize. Around 247 BC, Wei Yi came to the state of Qin, and was appreciated and reused by the king of Qin for his outstanding military talents. He proposed the policy of "merging the vast and using one system" to weaken the six states of Shandong through the strategy of connecting and horizontating, and then realize the unification of the Qin state under the world, which greatly enriched and perfected Qin's foreign expansion policy.
During his time at the Qin court, he assisted Qin Shi Huang in formulating a series of key strategic decisions, including how to divide and dismantle rival alliances and how to effectively integrate resources for war. His book "Wei Xuanzi" brought together the essence of his military theory and had a major impact on the development of ancient Chinese military thought.
Wei Yi is not only an outstanding military strategist, but also a strategic master who deeply understands the changes of the current situation and can grasp the historical context. His life story vividly shows how an outstanding wise man used his wisdom to advance the course of history in the context of the Warring States disputes, thus becoming an important driving force behind the Qin Dynasty's eventual unification of the world. Wei Yi's deeds and contributions have undoubtedly left a strong mark in the long river of Chinese history.
