In the warring states era of constant strife, each country was under various pressures, some from diplomatic failures and national interests were damaged, such as the death of King Huai of Chu in the Qin state; there was pressure from the border war and the land was occupied, such as Wei Han was attacked by the Qin people and cut the land for peace; there were also from the dispute between the crown princes in the DPRK and the chaotic war between the secretaries of power, such as the King Wuling of the Zhao State imprisoned for his courtiers and died in the sand dunes, and so on, so it is not easy to be the prince of the Warring States era, and it is even more difficult to be the monarch of a weak country. Even the Zhou Tianzi family could not resist the huge pressure from the Qin people to move east, and the Eastern Zhou Jun specially ran to the King of Qin Zhaoxiang to worship the Qin State, and the kind of pressure that was both loud and tangible had made Tianzi and the princes gradually become restless, and even every day was full of sorrow.
So what is the most common method for how to decompress? Weak countries such as song, Lu, Zhongshan and other countries are already at the end of their strong crossbows, and can only rely on the implementation of changes in the country to slow down the speed of national decay. Those powerful courtiers did not regard the princes as superiors at all, for example, the Jisun clan of the State of Lu later established itself as a monarch in Feidi and became a state within a state of the State of Lu, and the way the monarchs of these countries could take was silence, in order to absorb the pressure from the outside, to be able to participate without participating in foreign wars, and to minimize diplomatic activities. But what about the powerful? They have always pursued power and war, and the princely powers such as Qi, Zhao, and Chu are trying to encroach on the surrounding countries to buffer the situation, such as the State of Qi, which destroyed the State of Song, the State of Zhao attacked the State of Zhongshan, and the State of Chu vigorously launched a war against the State of Lu.
In the earliest times, especially in the Spring and Autumn Period, the entire princely states believed in the so-called "Zun Wang Zhiyi", although the Chu state was a powerful country, but in the treatment of the Lu state of the problem is more or more co-opted, the Chu state hopes to use the attitude of the Lu state to change the Central Plains people's view of the Chu state. And the Lu people were mixed between Qi, Jin, and Chu, and for a long time under the inducement of interests, they were indeed loyal vassals of the Chu state. Later, the State of Qin was strong, the State of Jin was divided into Han Zhao Wei, and the real and sustained strength of the country was Only Qin, Qi, and Chu, because the State of Lu was far away from the State of Qin, so the State of Lu most of the time became a victim of Qi chu's hegemony. Especially after the Chu people were attacked by the Qin people in an all-round way, most of the Chu forces migrated north, and the State of Lu became an important target for the Chu people to alleviate external pressure. This situation occurred roughly during the reign of Duke Ruben.
Duke Wen of Lu was the penultimate monarch of the State of Lu, who remained a figure without a sense of existence, during which the Qin people's foreign wars were intensifying, the Three Jin Regions such as Han and Wei had all surrendered, and the Zhao State was also expanding eastward, and the containment of the Qin people was weak. Therefore, the Qin people were able to free up time to stabilize the rear, the Qin people attacked the southern Shu state during this time, using the Shu state as the rear granary of the Qin state's foreign conquest, and at the same time, the Qin people accelerated the invasion war against the Chu state, and the tragic death of the king of Chu Huai became a turning point in the development of the Chu state, and since then the Chu people have been trapped in a difficult situation inside and outside for a long time, and the Qin people have been in a difficult situation inside and outside for a long time, and the Qin people have taken up the tiger and wolf division in vain, and destroyed the city and pulled down the village to break through dozens of cities and pools in the Chu state, and finally attacked the capital of the Chu state, and the Chu royal family led their loyal sons and forces to move the capital to the north. The sorrow of the Chu people must finally find an exit.
Duke Lu Wen reigned for more than twenty years, but in these twenty years more than twenty years appeared in the history books more than the Qin people attacked the war, the historical data of the Lu people can be said to be not even a single word, which shows that Lu Wengong has few major deeds during his reign, and even if he tries to make a difference, it is difficult to break through the difficult situation of the strong enemy on three sides, the western Qin forces have reached the land of Song Wei at this time, the Northern State of Qi is causing trouble at any time on the border of the State of Lu, the People of the State of Chu have lost their old land, and the main military forces are deployed in the south of the State of Lu. The end of the Lu people may be coming.
