said that Chen Deng said the name of this person, Liu Bei was surprised and turned his worries into joy.

It turned out that this person was a Confucian scholar and master of scripture in the late Eastern Han Dynasty, and he was not only famous and respected by later generations Zheng Xuan, but also a famous scholar and thinker in the history of our country.

Zheng Xuanzi Kangcheng, a native of Gaomi (now Gaomi, Shandong), his grandfather Zheng Ming and father Zheng Jin only worked in the countryside as farmers, and their families lived relatively poorly.

Zheng Xuan has been intelligent since he was a child, and he was proficient in arithmetic at the age of eight or nine; Zheng Xuan is dedicated to learning, pragmatic by nature, not vain, when he was eleven or twelve years old, he went to his grandfather's house with his mother as a guest.

At that time, there were a lot of guests, and the more than ten guests present were all dressed beautifully, dressed up in a new way, and all of them spoke refreshingly, boasting, and seemed to have a lot of status and style, but Zheng Xuan sat silently on the side, and his identity and talent seemed to be incomparable.

Seeing this, the mother felt that her face was gloomy, so she secretly urged her to show her face, show some talent, show some generosity and spirit.

Zheng Xuan disagreed, saying that these vulgar scenes were "not what I wanted, not what I wanted".

In fact, when Zheng Xuan was twelve or thirteen years old, he was able to recite and tell the "Five Classics" of Confucianism in "Poems", "Books", "Yi", "Book of Rites", "Spring and Autumn", and also liked to study astronomy, and mastered some techniques such as "Fortune Hunting", "Wind Angle", "Hidden Technique" and other methods of speculating on good luck and evil based on changes in weather and wind direction; At the age of sixteen, he was not only proficient in Confucian classics, familiar with ancient classics, but also wrote good articles, and was known as a prodigy by the world; When he was eighteen years old, due to his poor family and poor life, his parents and brothers were forced to make ends meet and did not allow him to study for many years. He had to go out of office to serve as a country husband.

Zheng Xuanren was diligent, very serious, and cared for the orphans, and won praise from the township, and was soon promoted to the township.

Zheng Xuan was not satisfied with the work of the village officials, and was dedicated to academic research, and while serving as a village official, he also used all the opportunities available to study hard, and did not go home on every holiday, but went to the school to ask his husband for various academic questions.

My father was very opposed to this, and repeatedly reprimanded and reprimanded him.

Unmoved, he continued to study tirelessly, and by the age of twenty-one, he had a well-read book, a profound foundation in scriptures, and was proficient in the study of calculus and diagrams, as well as actuarial arithmetic.

At that time, the famous man Du Mi served as Taishan Taishou and Beihai Xiang, and when he went to Gaomi to inspect Zheng Xuan, he knew that he was a rare talent, so he was promoted to a county official, and soon recommended him to enter Taixue, which created an opportunity for him to continue his study and further study.

His Taixue teacher, the Fifth Yuan Xian, was the surname of Jingzhao Pingling (now Chang'an, Shaanxi) at that time, and was a very learned doctor of scripture.

Zheng Xuan learned from the fifth Yuan Xian, and successively learned "Jingshi Yi", "Ram Spring and Autumn", "Three Unified Calendars", "Nine Chapters of Arithmetic", etc., all of which have reached the level of proficiency.

Among them, "Jingshi Yi" was written by Jingfang of the Western Han Dynasty, and "Ram Spring and Autumn" was written by the Warring States Ram Gao and the early Western Han Dynasty, both of which are important classics of modern literature and classics. "Santong Calendar" is a calendar written by Liu Xin of the Western Han Dynasty, and "Nine Chapters of Arithmetic" is said to have been written by Zhou Gong of the Western Zhou Dynasty. Both of these books are important works on the study of almanacs.

In the next ten years, it was Zheng Xuan's school days.

He studied the fifth yuan successively, and from Dongjun Zhang Gongzu as a teacher, he studied "Zhou Guan", "Book of Rites", "Zuo's Spring and Autumn", "Han Poems", "Ancient Texts and Books", etc., which are all important classics of ancient literature and classics except for "Rites" and "Han Poems".

After Zheng Xuan learned the important scriptures of the two schools of modern and ancient literature and classics from the Fifth Yuan Xian and Zhang Gongzu, he was not satisfied, and he received employment from Chen Qiu and studied the "Law Order".

During this period, he also traveled to You, He, Yan, and Henan Prefectures for the purpose of learning the Ming scriptures and showing the discipline, visited famous Confucianism, turned to many teachers, humbly sought advice from learning, and discussed academic issues with teachers and friends.

After the establishment of the year, because of reading thousands of books, traveling thousands of miles, tirelessly working hard, and diligently seeking the Tao, Zheng Xuan has been called a scholar with deep attainments.

His knowledge in Shandong can be said to be second to none and unparalleled.

Although Zheng Xuan has learned five cars, he is not satisfied.

When he felt that there was no one to consult the scholars of Kanto (referring to the east of Hangu Pass), he left his homeland through his friend Lu Zhi and traveled thousands of miles west to Guanzhong, where he became a teacher.

Ma Rong was the most famous master of scripture at that time, and he was very knowledgeable, and he had memorized Confucian classics, so that the ancient scriptures had reached a state of increasing maturity.

Ma Rong has thousands of disciples, and there are more than 400 people who have been following him for many years, and more than 50 of them are excellent.

Ma Rong is arrogant and exquisite, although there are many disciples, but only a few high-level disciples are taught in person, and the rest are taught by these high-level disciples.

Zheng Xuan joined the school, and was not valued by Ma Rong for three years, and he never even had the opportunity to see Ma Rong, so he could only listen to his high-level disciples, but Zheng Xuan did not relax his study because of this, and still studied and recited day and night, without slackening.

Once, Ma Rong and some of his high-level disciples were calculating the problem of the heavens, but they encountered difficulties and could not solve them by themselves.

At this time, someone said that Zheng Xuan was good at mathematics, and Ma Rong knew about it, so he summoned Zheng Xuan to meet.

Zheng Xuan quickly and satisfactorily solved this difficult problem on the spot, which made Ma Rong and the disciples present shocked, and Ma Rong said to Lu Zhi: "You and I are not as good as him!" ”

Since then, Ma Rong attaches great importance to Zheng Xuan, and Zheng Xuan has sought advice from Ma Rong one by one on the difficult problems found in his usual study and unsolved.

Zheng Xuan studied with Ma Rong for seven years, and because his parents needed to return to his hometown because of their old age, he said goodbye to Ma Rong and returned to his hometown.

Ma Rong already felt that Zheng Xuan was a great talent at this time, and even surpassed himself, and said to his disciples with deep emotion: "Zheng Sheng is going now, and I will go to the east!" This means that the Confucian academic ideas inherited by him will definitely be carried forward in the Kanto region due to the spread of Zheng Xuan.

Zheng Xuan, who is already in his forties, has become a master who is proficient in modern and ancient scriptures, and he knows everything from a hundred schools.

After he returned to his hometown after studying from Ma Rong, hundreds of people from near and far came to him to worship him as a teacher and listen to his lectures.

At that time, his family was still very poor, so he "cultivated Donglai", farming to make a living, and teaching disciples.

Implicated in the "disaster of the party", Zheng Xuan was imprisoned from the age of 45 to the age of 58 before receiving a pardon, which lasted for 14 years.

During this period, he broke the family law of classics, annotated and wrote "more than 100,000 words", founded "Zheng Xue", and made unparalleled outstanding contributions to the history of the development of Chinese classics.

"Zheng Xue" gradually became the Confucianism of "the sect of the world", and Zheng Xuan became famous because of this.

After the outbreak of the Yellow Turban Uprising, the imperial court was forced to grant amnesty to the party.

After the ban on the party was lifted, the imperial court had already heard of Zheng Xuan's name, so they vied to hire him to serve in important positions.

However, Zheng Xuan sought fame rather than office, was ashamed to be with his relatives and eunuchs, and was unwilling to get involved in official careers, so he repeatedly refused to be recruited and devoted himself to writing books and lecturing.

Cao Cao went to Yanzhou to conquer the Yellow Turban Army, and Zheng Xuan avoided chaos and went to Xuzhou.

When Xuzhou Mu Taoqian heard that Zheng Xuan had arrived, he welcomed him very much and received him as a gift of mentor and friend.

Zheng Xuan settled himself in a stone house under the Chiyan Rock in the mountains of Nancheng, and rarely showed up, still working day and night, tirelessly studying the Confucian classics and commenting on the Book of Filial Piety.

Zheng Xuan lived in Xuzhou for five or six years, when Kong Rong was the minister of the Beihai Sea, and he had special respect for Zheng Xuan.

When Zheng Xuan heard that Beihai was besieged, when Tai Shici asked Liu Bei for help, he ordered his son Zheng Yien to lead his family soldiers to rescue him, but he was besieged and killed at the age of twenty-seven.

After Zheng Yien's death, he had a posthumous son, and Zheng Xuan was named Xiaotong because of his similar hand prints.

Yuan Shao was also the governor of Hebei, Qing, You, and the four prefectures, and had a large banquet guests, and Zheng Xuan was invited to attend.

During the banquet, some of the so-called "Haojun" questions were answered correctly, and the guests were all impressed.

Yuan Shaonai promoted Zheng Xuan as Maocai, and asked Zheng Xuan to be the general of Zuo Zhonglang, and led the Shangshu affairs, but Zheng Xuan politely refused.

Dedicated to the emperor Zheng Xuan as the great Si Nong, ranked in the Jiuqing, to take a ride on the car, and the county magistrates sent them off.

After Zheng Xuan paid homage at home, he took a car to Xuchang, but immediately asked to return to his hometown under the pretext of illness, passing through the old site of Xuzhou temporarily.

Liu Bei was very surprised when he heard that Chen Deng recommended Zheng Xuan's book to Yuan Shao for help, because Zheng Xuan was too famous and respected by Yuan Shao, and he had also heard Zheng Xuan's lectures, and he was also regarded as his own teacher, so he followed Chen Deng to Zheng Xuan's residence to explain his intentions.

Zheng Xuan remembered that Gongsun Zhan and Liu Bei had studied under their friend Lu Zhi, and had also listened to their own lectures. ”

This time, Liu Bei followed Chen Deng to his home to ask for a book, saying that Lu Zhi passed away and Gongsun Zhan died in battle, Zheng Xuan couldn't help but feel sad: "This year is in Mao, that is, the Year of the Rabbit, I am seventy-three years old; The coming year is in Chen, Gengchen is the year of the dragon, and it should be the sage. ”

Liu Bei was puzzled, so Zheng Xuan said to Liu Bei: "I feel unwell, I'm afraid I'm going to be sad." You have the heart of the world, and you should do it yourself well and live up to the expectations of the people. ”

After that, repair a book and hand it to Liu Bei.

Liu Bei got a letter asking Yuan Shao for help, said goodbye, and expressed his gratitude to Chen Deng, and he was reluctant to give up.

Although Chen Deng admired Liu Bei, he did not forget his duties, always concerned about the people of Guangling, and at the same time knew that he had broken Cao Cao's plan to eradicate Liu Bei and murdered Che Zhou, if Cao Cao knew about it, he would definitely be blamed, so he said goodbye to Liu Bei and said: "I hope that the king will take care of himself more in the future, no matter when and where, he will be people-oriented, and treat the people well, so as to be invincible." ”

Then go home and explain it to your father.

Although the father agreed with his son to help Liu Bei, he was afraid that his son would cause trouble in vain and suffer misfortune, so he urged his son to leave quickly.

Chen Deng bid farewell to his father, and then hurried back to Guangling to take office.

After Liu Bei waited for Chen Deng to leave, he sent Sun Qian to see Yuan Shao with Zheng Xuan's letter for help day and night.
