Does the subject want to ask, "Struggling youth is the spirit of endless learning, which sentence is in the preface that Song Lian sent to Dongyang Ma Sheng?" Not only is coronation beneficial to the way of saints, but it also suffers from the lack of masters, celebrities and travel. The smell of a hundred miles away is called asking questions to your hometown. According to the "Preface to seeing Ma Sheng off to Yang", this ancient prose is not only the crown, but also benefited from the worship of sages, suffering from the lack of masters, celebrities and travel, and tends to be a hundred miles away. After writing this sentence, I admire the sage theory even more, but I also suffer from being unable to associate with knowledgeable teachers and celebrities. Once I walked (ran) a hundred miles and asked my fellow villagers for advice with scriptures in my hand. Preface to seeing Ma Sheng off to the East is a preface written by Song Lian, a writer in the Ming Dynasty. In this preface, the author describes his early experience of seeking advice with an open mind and studying hard, vividly and concretely describes the difficulty of borrowing books and seeking teachers, and the pain of running around in cold and hunger, and compares it with the superior conditions of the students in the business school, which strongly shows that whether or not academic achievements depend mainly on subjective efforts, rather than the level of talent and the advantages and disadvantages of conditions, so as to encourage young people to cherish a good reading environment and concentrate on their studies. The full text is rigorous in structure, meticulous and thoughtful, contrastive in reasoning, detailed in narration and vivid and touching to read.
