What kind of era is the Spring and Autumn Period and the Warring States Period?

First of all, it must be clear that the Spring and Autumn Period and the Warring States Period are two periods, and in order to summarize the history of this war, our descendants collectively call it the Spring and Autumn Period and the Warring States Period.

In fact, the Spring and Autumn Period was named after Lu Chunqiu, a chronicle of Lu Nian compiled by Confucius. Generally speaking, it refers to 770 BC to 476 BC, and the Warring States Period refers to 475 BC to 22 BC1year. In fact, the specific time should be counted from the time when Han, Zhao and Wei were divided into Jin until Qin Shihuang unified the world, that is, from 403 BC to 22 BC1year. In the Spring and Autumn Period, there were nearly 170 countries, all of which were descendants of the vassal states that split after the destruction of the Shang Dynasty in the Zhou Dynasty, but by the Warring States Period, there were almost only seven countries left, that is, the so-called Seven Heroes of the Warring States. They are Qin, Zhao, Wei, Han, Qi, Yan and Chu.

In fact, the Spring and Autumn Period and the Warring States Period is an era in which a hundred schools of thought contend, rituals collapse and music breaks down, and wars continue. In this era, heroes come forth in large numbers, and the decline of the strong is reincarnation. Almost every country has a period of prosperity, but it declined for various reasons and was finally unified by Qin. This period of history can be said to be the most important one in China's history, because in this period of history, not only the theory of "hundred surnames, thirty-six occupations and countless works" that we are talking about appeared, but also the former slavery was changed, and we entered the feudal system. In addition, it laid the foundation for soldiers to use their troops cunningly. In the past, when fighting, the two sides first agreed on a time and place, then deployed together, and finally beat gongs and drums to move forward. In the Spring and Autumn Period, this foolish practice was eliminated by various strategies and tactics, and a generation of famous soldiers appeared, such as Sun Wu, Sun Bin, Wuqi, Tian Lei and Le Yi. The earliest commercial war appeared in this period, which established the theory that only rich countries could build Qiang Bing.

In a word, the most wonderful thing in China's history is the Spring and Autumn Period and the Warring States Period.

All the above are my personal opinions, typed word for word.
