The full-text analysis and the general content and central idea behind it.

At the beginning of the article, the father and son went home together to attend the funeral. On the surface, it seems that it only shows the beginning of the matter, and has nothing to do with it. This opening actually sets a gloomy atmosphere and a sad environment for the whole novel, poetry and literary works, in which the father's back appears. This gloomy atmosphere and sad environment are in sharp contrast with the full warmth of the father to his son, showing the loftiness of the father's love. At that time, my father was bereaved, unemployed, pawned and borrowed money. However, even in this bleak situation, the father did not complain, and always loved his son and did one thing after another for him. What kind of things are those? There are some things he doesn't need to do, such as sending his son to the train; Some things are not what he has to do or what he can do, such as climbing the railway to buy oranges. But in my father's mind, these things must be done by myself, which is his unshirkable responsibility, so it is easy to feel uneasy not to do them. He tried his best to do it one by one, so seriously, so naturally and so willingly. For example, crossing the railway and climbing up and down are obviously so laborious and difficult. However, after finishing, he "jumped on the dirt on his clothes and felt very relaxed." In order to take good care of his son, he ignored any disaster and fatigue. What a father does for his son in this difficult adversity is many times more precious than what he usually does, especially in the good times. The father's back is different from the ordinary back that can be seen everywhere, but full of feelings and profound meanings.

The father sent his son to the station for a while, and then wrote letters from the father and son. On his father's side, he thought twice that he had to see his son off in person, but on his son's side, he didn't think so. What he thinks is that he is "twenty years old and has been to Beijing two or three times. It doesn't matter." He didn't care much about his father's farewell and didn't understand his father's mind. So, the father bargained with the porter, and the son "always felt that he didn't speak well"; The father asked the waiter in the car, and the son laughed at him for being "pedantic". A father is sophisticated, but he knows better than his son that "they only know money, and it's really useless to entrust it to them", but it is because he loves his son that he knows what he can't do. However, the son thinks his father's behavior is offensive, which makes him feel embarrassed. This is naturally not that the son does not love his father, but that the son does not understand his father after all. Later, the back appeared, and the son clearly saw that his father was doing incompetent work for himself, and finally fully understood his father's love for himself, so that he shed tears. This is a tear mixed with gratitude, regret and shame. The differences and changes in the inner feelings of the father and son in this process make the article ups and downs, and also show the touching power of the father's back.

Father bought oranges and finally left. At this point, the article seems to be over. But then I wrote a story about my father's sufferings in recent years. This paragraph can be said to be a deepening of the following description. On the one hand, it played a role in echoing the original atmosphere and emotional appeal, reflecting my father's bumpy life path and revealing the bleak society at that time, on the other hand, it continued to strengthen my back image. In his later years, his father was in a bad situation. Sometimes he treats his son worse than before. He is old and weak. He can't work hard for his son as he used to, but his heart of loving and caring for his son hasn't changed. "He just thought of me and my son." If a father used to do his best for his son, now in his later years, he has done it. The son saw his father's back in crystal tears. It should be said that the figure in his mind at the moment is not only the reappearance of his father's figure in the past, but also the figure of his old father. This figure entrusted his son's deep yearning for his father and deepened the reader's impression of the full text.
