Although the Northern Song Dynasty ruled the world with civilized policies and was not strong in national power, there was no atmosphere of humiliation and seeking perfection, and there was no sad mood of carnival at the end of the world. The national situation is different, and the requirements of the cultural context are also different. The writing style of the Northern Song Dynasty was splendid and free of pretentiousness. It can be said that freedom of thought allowed a hundred flowers to bloom. The imperial party of the Southern Song Dynasty avoided important matters and pretended to be relaxed just for the emperor's fun. They had no spirit of life and were weak and incompetent! However, those who are patriotic and nostalgic who want to return to their homeland but have no hope feel sad and sigh in vain.
