"Qin" means celery. Liezi Yangzhu: Some people praised the rich villagers for their delicious celery. As a result, the rich people ate it, but their mouths were swollen and their stomachs were troubled. Later generations used "offering Qin" to express their sincerity. Xin Qiji once wrote110 paper on165, also known as "Ten Theories of Meiqin", stating the grand plan of resisting gold, saving the country, recovering lost land and unifying China. Xin Qiji hoped that the small court in the Southern Song Dynasty would not be partial to the corner of the south of the Yangtze River, and was determined to recover lost ground, expressing the great ambition of "people are dead set". Now Xin Qiji's Ten Treatises on Meiqin and Ten Treatises on Meiqin are dedicated to the emperor. Xin Qiji himself is very modest, saying that the ten cures are only what he thinks is good, and the emperor doesn't necessarily like them-just as the Song people like celery-in fact, the emperor doesn't. Speaking of this "beautiful Qin", people usually say "Su Li". Xiaomi is Xiaomi. According to historical records, after Zhou Dong moved, Zhou people returned to their old capital, saw the ancestral temple razed to the ground, and were saddened by the subversion of the country. Therefore, the Book of Songs includes the chapter of "Separation of Millet". Since Xin Qiji put forward "Ten Treatises on Meiqin", people have regarded "Meiqin" and "Sad Millet" as synonymous with worrying about the country and the people and subverting the country. Since then, Meiqin has a specific and far-reaching significance. Li Zhi once put forward the theory of the relationship between courage and fear and region in the first chapter of Taibai Silence, while Xin Qiji said in the chapter of Autonomy: "Everyone in the world said,' There is a certain trend between the north and the south, and Wu Chu's fragility is not enough to compete with the Central Plains'." "The question retorts, and" is it possible for the North and the South to be brave and timid? "The conclusion is that, unlike Li Zhi, Xin Qiji's purpose is to hope that the Southern Song Dynasty court can get rid of the prejudice of the North and South, and then be autonomous; The former has important theoretical value, while the latter has important practical significance. From the same source and different streams, each has its own strengths. As for what he said in the article "Investigation": "If the two enemies are deadlocked and can't get their feelings, they will doubt it, and if they doubt it, they will be afraid and unknown; If you have your feelings, you must decide. If you decide, you must not be confused. Those who listen to self-disturbance without confusion always have the power in me and the enemy actually suffers. " This theory can be said to be the essence of the theory of military reality. This is the beauty of the empty camp plan, which is safe and stable. But Xin Qiji was the first person to tell the truth and get to the point.
