About the start time of the Warring States era, there is no unified division, but there are three main statements:
The first 476-475, this is the statement of Zhou Zun, because this year is Zhou Yuan Wang Yuannian (the error caused by Zhou Jingwang). "Zuo Chuan · Ji Gong 19 Years": "Winter, Uncle Qing is like Jingshi, Jing Wang's collapse." Taking Zhou Jing Wang in forty-four years, the next year is Zhou Yuan Wang Yuannian, for the Warring States beginning.
The first 468, in this year, it is because it is Zhou Xing Wang's first year, and the second is because this year is the deadline of "Zuo Chuan", so it is continued.
The first 403 years, this year, Han Zhao Wei Sanjia from Jin Guo independence, league, and the group is competed, and "Conduct" will be started.
In order to divide the integrity of the period, it is generally the time since 475 starts as the start of the Warring States.

The so-called Warring States is actually starting from this year. From then on, the stage of the group is, which is generally the beginning of the mid-term of the Warring States in the year.
The second phase of 63 years is the time of Wei Guo's dominant, and it is also the time of the other vassational countries:
before 403, Zhao Guoli is beginning to change, Zhao The country began to be strong;
before 387, Wu Qi from Wei Zi Chu implemented the implementation of the change, after the rest of Chu Su, Chu Xuanwei's recuperation, Chu State began to be strong;
