In the 5,000-year-long history of Chinese civilization, countless outstanding thinkers and politicians have emerged. Each of them carries their own unique ideas, and they travel between the six countries, either warmly welcomed or hit a wall. Su Qin, Zhang Yi, Kong Qiu, and Meng Ke were among the best, and their life experiences and ideas not only influenced the society at that time, but also had a profound impact on later generations.
1. Human desires that fit in time: Su Qin and Zhang Yi's vertical and horizontal techniquesSu Qin and Zhang Yi were famous columnists during the Warring States Period, and with their outstanding wisdom and eloquence, they lobbied among the six countries and devoted themselves to combining vertical and horizontal strategies in order to achieve their respective political goals. Their sharp-tongued, witty, and well-versed minds often make it easy for them to impress monarchs and become guests of honour in various countries. The strategy of "joint vertical" proposed by Su Qin was aimed at uniting the six countries to jointly fight against the powerful Qin state in order to safeguard their respective interests. Zhang Yi, on the other hand, advocated "Lianheng", that is, to balance the other five states by forming an alliance with Qin, so as to achieve the hegemony of Qin. Although the strategies of the two were different, what they had in common was that they both firmly grasped the real needs of the society at the time – that is, the security and interests of the country. Their remarks and ideas were in line with the desires of the monarchs of various countries at that time, so they were widely recognized and supported. 
2. The eternal principle of heaven: the Confucian way of Confucius and Meng KeUnlike Su Qin and Zhang Yi, Confucius and Meng Ke represented the orthodoxy of Confucianism. The concepts of benevolence, courtesy, and loyalty advocated by them are in-depth insights into human nature and deep reflection on society. However, in such a turbulent and profit-oriented era as the Warring States period, their ideas seemed somewhat out of place. The idea of "benevolence" put forward by Confucius advocates the use of benevolence to govern the country and handle interpersonal relations. He believed that social harmony and stability could only be achieved through benevolence. However, in an era like the Warring States, such an era of the jungle is the strong, it is obviously difficult for this idealized proposition to be widely recognized. Similarly, Meng Ke's ideas such as "Theory of Sexual Goodness" and "Benevolence, Righteousness, Propriety, and Wisdom" also seemed out of place in the society at that time. Their rhetoric and ideas are seen more as an idealistic pursuit than as a realistic solution. 
3. The sweet words of prostitutes and villains and the cold words of women and righteous peopleSu Qin and Zhang Yi's words are like the sweet words of a prostitute villain, although they are beautiful but lack depth. Their words are full of ** and interests, and it is easy to make people's hearts move. And the remarks of Kong Qiu and Meng Ke are like the cold words of the righteous women, although they are cold but full of power. Their words reveal concern for humanity and responsibility to society, but this kind of profound insight and firm belief is often difficult for the world to accept. However, it is precisely these two distinct statements and propositions that constitute the richness and diversity of Chinese civilization. Su Qin and Zhang Yi's vertical and horizontal techniques, although short-sighted but practical, provided a powerful ** for the political struggle at that time. The Confucian way of Confucius and Meng Ke, although long-term but idealistic, provided a solid ideological foundation for the social progress of later generations. 
Fourth, the wise man's different paths and the same destination: the choice and inheritance of historyAlthough Su Qin and Zhang Yi and Kong Qiu and Meng Ke have completely different ideas and ideas, they are all based on in-depth insight into society and human nature. Each of them carries a unique concept and shuttles between the six countries, leaving a deep historical imprint. In the long river of history, Su Qin and Zhang Yi's vertical and horizontal techniques may have been glorious for a while, but in the end they failed to become the mainstream. The Confucian way of Confucius and Meng Ke, although once neglected, eventually became the essence and soul of Chinese civilization. This may be because, in the long course of history, people have gradually realized that true wisdom and strength do not come from short-term interests and interests, but from in-depth insight into human nature and deep reflection on society. Today, when we look back on this period of history, we cannot help but have a deep respect for these wise men. Each of them carried a unique concept and shuttled between the six countries, which not only left us with valuable spiritual wealth, but also provided us with profound inspiration. In this era of rapid change, what we need is not only short-term interests and social responsibility, but also care for humanity and responsibility for society. Only in this way can we leave a deep mark on the course of history and become truly wise men. 5. Conclusion: The Light of the Wise and the Enlightenment of the HereafterSu Qin, Zhang Yi, Kong Qiu, Meng Ke, these wise men in history, although their thoughts and propositions are different, they all provide us with profound enlightenment. They tell us that true wisdom and strength come from deep insight and reflection on human nature and society. In this era of rapid change, we need to keep learning, thinking and exploring in order to become truly wise. At the same time, we should also recognize that the selection and inheritance of history is a long and complex process. In this process, some ideas and propositions may be temporarily ignored or ignored, but as long as they truly meet the needs of human nature and the development trend of society, they will eventually be recognized and inherited. Therefore, we should maintain an open mind and a critical spirit, constantly learn and explore new ideas and concepts, and contribute to the progress and development of society.
