Liu Yiqing (403- 444), born in Pengcheng (now Xuzhou, Jiangsu), was a writer in the Southern Song Dynasty. The imperial clan of the Song Dynasty attacked King Linchuan and made him the secretariat of Jingzhou. Eight years in politics, good results. Later, he was appointed as Jiangzhou Secretariat. After a year in office, Wen Di was angered by his sympathy for Wang Yikang, a disgraced official, and was transferred back to Beijing as the secretariat, governor and blessing officer of Nanjing. Soon, Yuan Jia abdicated due to illness and died in Jiankang (now Nanjing) in 2 1 year. Liu Yiqing was gifted since childhood and loved literature. Besides Shi Shuo Xin Yu, there is also a strange novel You Ming Road. Shi Shuo Xin Yu was compiled by a group of people he organized.
all one's life
Liu Yiqing, the nephew of Emperor Wu of Liu Song, is outstanding among emperors and highly valued.
(1) Quiet and cloudy period 15-30 Liu Yiqing rose to its peak at the age of 15. Among them, he served as secretary supervisor, in charge of books and works throughout the country, and had the opportunity to contact and exhibit royal classics, which laid a good foundation for the compilation of Shi Shuo Xin Yu. At the age of seven, he was promoted to the senior minister of Zuopiao Society (equivalent to the deputy prime minister), which was a very important minister, but his uncle Liu Yu set the precedent. Therefore, Liu Yiqing is also afraid of an accident. At the age of 29, he begged for mercy and was relieved of his position as Zuo Piao.
(2) During the Jingzhou period, Liu Yiqing served as the secretariat of Jingzhou from 30 to 37 years, and made great achievements. Jingzhou is an important town in the upper reaches of the Yangtze River, where it has lived a stable life for eight years.
(3) During the Jiangnan period, Liu Yiqing served as the secretariat of Jiangzhou and Zhou Nan from 37 to 42 years. At the age of 38, he began to compile Shi Shuo Xin Yu, and had frequent contacts with literati and monks at that time. He died of illness in the capital at the age of 42. Liu Yiqing is a scholar and politician who is "pure in nature, lacking in lust and loving literary significance". Although he held an important position all his life, his achievements were lacking. Apart from his lack of enthusiasm, the most important reason is that he is unwilling to get involved in the power struggle between Liu and Song.
Shi Shuo Xin Yu
A pure nature, lack of lust, love literary significance. It is suitable to gather scholars and writers from far and near. At that time, famous scribes such as Yuan Shu, Lu Zhan, He Changyu, Bao Zhao and others were treated with his courtesy. Shi Shuo Xin Yu has eight volumes, three volumes and thirty-six volumes. Shi Shuo Xin Yu may have been polished by him and other scholars, and it is a collection of local novels. This book records anecdotes from the Han and Wei Dynasties to the Eastern Jin Dynasty. Although it is a few words, the content is very rich, which widely reflects the lifestyle, mental outlook and atmosphere of speaking freely and celebrating the birthday of the gentry in this period. This book has a far-reaching influence on the development of later note novels, and there are countless works written after imitating this book, which are self-contained in ancient novels. Many stories in the book have become the materials of later dramas and novels, or the allusions commonly used in later poems, and have an important position in the history of China literature. Mr. Lu Xun called them "textbooks for celebrities". Shi Shuo Xin Yu was originally 8 volumes, but now it is 3 volumes, which are divided into 36 subjects, such as morality, speech, politics, literature, founder, magnanimity, knowledge and appreciation. It mainly records the speeches of scholars in Jin Dynasty. Mr. Lu Xun once pointed out: "This argument originated from the discussion in the Han Dynasty. At the end of Han Dynasty, politics was dark. Generally speaking, celebrities talk about politics. At first, they were very influential in society. Later, he was jealous by the rulers and was gradually killed. Kong Rong and Mi Fei, for example, were both killed by Cao Cao, so at the end of the Jin Dynasty, they dared not talk about politics and turned to Hyunri. If you don't talk about political affairs, it will become the so-called clarification. However, such celebrities were still very influential in the society at that time. If you can't talk about it, it seems that you are not qualified to be a celebrity. The book Shi Shuo can almost be regarded as a textbook for celebrities. "
The original text of Yong Xue.

Yong Xue's Translation
On a cold snowy day, Dr. Xie gathered his family together and explained poetry to his son and nephew. Soon, it snowed heavily, and the teacher said happily, "What is this heavy snow like?"

Chen Yuanfang, the eldest son of Qiu, was playing outside the door when he was seven years old. The man asked Fiona Fang, "Is your father at home?" Fiona Fang replied, "If you haven't come for a long time, he has already left." The man lost his temper and scolded, "What a shame! I asked someone else to go with me, but I left without them. " Fiona Fang said, "You have an appointment with my father to start together at noon. When noon arrives, it is not trustworthy. " It is impolite to scold your father for your son.

Write a feeling of gratitude after reading 1000 words. Oh ~ ~ urgent ... gratitude and dedication.
But how much love has an inch of grass, and I got three spring rays. "Who knows that every grain of Chinese food is hard?" These poems we recited when we were young were all about gratitude. "A drop of water is rewarded with a spring" and "a ring of grass grows long, and gratitude is repaid", an ancient idiom that has been circulated in China for many years, tells us to be grateful. Gratitude is the basic moral standard that everyone should have, and it is the minimum accomplishment of being a man. Many people, many things, blame comes from not knowing how to be grateful, crows have the meaning of feeding back, sheep have the grace of kneeling, don't know how to be grateful, and lose the emotional foundation of love. Learn to be grateful, thank parents for their upbringing, thank teachers for their teaching, thank classmates for their help, thank society for their care, and thank all those who treat and help themselves, even those who are not hostile to themselves. Gratitude is the embodiment of human kindness; Gratitude is a life attitude, a moral character and a heartfelt word. If people lack gratitude, it will inevitably lead to indifference in interpersonal relationships. People who don't know how to repay kindness but are ungrateful will be reviled as * * * villains, so everyone should learn to be grateful. Gratitude can not only make others happy, but also make yourself happy. Learning to be grateful is a little action to repay others; Learning to be grateful is to moisten the soul with moral nectar. Living in a happy day, our thoughts always fly far away. If we are red flowers, we will thank the green leaves for their dedication without regrets, and we will also thank the green leaves for their generosity and tolerance. If we are bees, we will thank the flowers for their generous and selfless gifts, and also thank them for their tolerance and kindness; If we are a big tree, we will thank the sun for giving me the energy of life and the earth for giving us solid support; If we are a small river, we should thank God, because you have given us a loud voice and tireless body. Gratitude is not only a beautiful emotion, but more importantly, it is the commitment to responsibility and the persistence in morality. When you are full of gratitude, you will think of return and dedication. Grateful to your parents, you kneel down and let them enjoy their old age; Thanks to your partner, you will "hold your hand and grow old with your son"; Thank your friends, you will treat each other with sincerity, with bitterness and with * * *; Be grateful for life, and you will love life and repay society. Dear friends, when you eat delicious food, will you appreciate your parents' selfless care? When you sit in a comfortable classroom, do you appreciate the teacher's hard work? When you succeed on the stage, will you appreciate the support of your friends? Please don't be stingy with your gratitude. When you get the care of your relatives or friends, you can at least say "thank you" faithfully and return with a sincere smile. When others need help and support, you can also extend a warm hand with a tolerant attitude. Because, if you are grateful, you will cherish possession and happiness. To learn to be grateful is to learn to respect others and always appreciate their help; Learning to be grateful is to let you know that everyone is enjoying the happy life brought by others through their own efforts; To learn to be grateful, we must first have a grateful heart. Only by knowing how to be grateful can we know how to pay, and only by knowing how to pay can we be grateful. Learn to be grateful, cultivate humility, treat people who are weaker than themselves, and know how to bend down and lend a helping hand; Learn to be grateful and have dedication. No matter what you do, you should put "public" first and be a selfless person. Only with a grateful heart can we know how to repay our parents' kindness in bearing and nurturing, how to cherish the kindness of school teachers in enlightenment and education, and how to cherish the kindness of society and nature. With a grateful heart, we can better understand our duties and responsibilities; With a grateful heart, there will be more tolerance and understanding, and less accusations and prevarications; With a grateful heart, there will be more harmony and warmth, less quarrel and indifference; With a grateful heart, there will be more sincerity and unity, and less deception and distraction. Learning to be grateful is an important step to realize yourself. Gratitude and gratitude to others are two habits leading to success. Expressing gratitude to others is the highest expression of respect and politeness, and it is also the safest way to establish and maintain interpersonal relationships. A person will feel happy because of gratitude. Grateful heart is the seed of peace, and gratitude is the harmonious factor between people. Without sunshine, there would be no warm days; Without rain and dew, there would be no bumper harvest; Without water, there is no life; Without parents, there would be no ourselves; Without affection and friendship, the world would be lonely and dark. When I was young, my parents held our hands. When we grow up, our parents hold us in their hearts. Grateful to my parents. It will make your family stay forever, make you feel satisfied psychologically forever, be full of confidence and vitality on the road of growth, and never fall behind.
