Let's talk about change first. The Spring and Autumn Period is the period when Zhou rites gradually disintegrated. The most remarkable effect was that the banner of respecting the king and resisting foreigners was put forward in the early Spring and Autumn Period, when the Rites of Zhou was still very sound. Zhou Li experienced many severe challenges in the later period, and it completely collapsed at the turn of the Spring and Autumn Period and the Warring States Period. Such as Lu, Sanjin and Tian in the Romance of the Three Kingdoms. , Zhou royal family has been powerless, the world * * * the image of the Lord has been lost. This is the most remarkable change in the whole Eastern Zhou Dynasty. In addition, Chairman Mao once said: Political power comes from the barrel of a gun. The key reason why Zhou Li can restrain the vassal states of the Western Zhou Dynasty is that Wang Ji is very powerful, which is several times more than the largest vassal state in territory, economy and number of troops, and enjoys the right to appoint governors of various vassal states. Each vassal state has a very limited territory and army. The lower the rank of male vassals, the less land and troops there are, and the vassal States have no right to conquer and annex them. People between countries (mainly between countries) are not allowed to walk around each other, and the scope of walking is limited to death. In this way, the patriarchal clan system of the Western Zhou Dynasty can be passed down from generation to generation, and the Zhou royal family always maintained absolute control over the princes. Until the Chinese rioted in Zhou Liwang, Zhou Xuanwang allowed the vassals to rectify their military power, and Zhou Youwang fought the vassals by fire. After these three changes, Ji Wang's land and army declined sharply. According to statistics, after moving eastward, the control area of Zhou royal family has been reduced to the level of second-rate or third-rate princes. At this time, the Zhou royal family should carefully handle the relationship with the princes, so as not to damage their authority, wait for their strength to recover, and use the contradictions between the princes to continuously expand their strength and become the real masters of the world again. But it happened that Zhou Lingwang ousted the most powerful vassal state at that time, that is, the bully in the Spring and Autumn Period, which directly triggered the war between Zhou and Zheng, and the result was a big defeat. This battle destroyed all the authority and myths of the Zhou royal family and let the world know the true strength of the Zhou emperor. Since then, the Zhou royal family began to decline. Back to the topic of the landlord, in the final analysis, military strength is the most important. The change of the slogan of respecting the king and resisting foreign countries shows that the strength of vassal States is getting stronger and stronger. After the baptism of the Spring and Autumn Period, small countries were basically eliminated, and the pattern of confrontation between big countries has taken shape. The Zhou royal family has become a small country like Wei and Zheng, and naturally it is no longer remembered by big countries. Even in the middle period, the two most powerful countries, Qin He Qi, were once called the Western Emperor and the Eastern Emperor, and they had already surpassed the level of Zhou Wang, so that no one mentioned the slogan of "respecting the king and rejecting the foreign countries".
