Why didn't Wei in the Warring States period have a sense of existence?

Nevertheless, Weiguo became one of the longest-lived vassal states. It was 838 years before and after the founding of the People's Republic of China, and there were 35 vassals. Uncle Kang made the capital sing when the People's Republic was founded. When Wei successfully moved his capital to Diqiu in 629 BC, divination said that he could establish his country here for 300 years. Later, Diqiu (Wei moved to Diqiu and changed its name to Puyang) really became a blessed land of Wei, where the people of Wei established a country for 388 years. Later, Wei was moved to (now Qinyang) county by Qin in fourteen years and lived there for several decades. During the Spring and Autumn Period and the Warring States Period, when many once famous vassal states were destroyed, Weiguo miraculously escaped numerous disasters and lived until Qin unified the world, but died. Many people find it hard to understand. The reason is that people think that this is because there are many talents to defend the country, just like "there are many generous and sad people in Zhao Yan since ancient times" and "there are many gentlemen to defend the country". Confucius traveled around the world for 65,438+04 years, including defending the country for 65,438+00 years, because there were many "gentlemen" who shared his tastes. Ji Zha, the younger brother of the King of Wu, once traveled around the world and was famous for his foresight. He concluded that "there are many gentlemen who defend the country, and his country is safe."
