When Emperor Jing of Han Dynasty, "Confucianism was not allowed, and Dou Taihou was good at Huang Lao Shu, so the doctor had an official question and refused to enter". Confucian scholars are still in the position of helping others, and Confucianism is the most excluded, which lasted until the early days of Emperor Wu of Han Dynasty. After Dou Taihou's death, Emperor Wu of the Han Dynasty began to use a large number of Confucian scholars, and some officials with Confucian thoughts were reused. Especially after Tian Wei became prime minister, "as Huang Lao said, there are more than 100 criminals and hundreds of literati." Then GongSunHong, a famous Confucian scholar, was promoted to the position of prime minister, the world was full of bachelors, Confucian politics rose to the dominant position, and Confucian scholars became officials in succession. Another sign of the miscellaneous use of Confucianism in the early Han Dynasty was to advocate filial piety and govern the country with filial piety. Since Hui Di, posthumous title, after the death of the Empress, has added a word of filial piety, called filial piety, filial piety, etc. There are also some princes and posthumous title, such as Qi Xiaohe, who use a word of filial piety to commend them for inheriting their father's business, obeying the instructions of their ancestors and becoming the foundation of the rulers. At the same time, officials who are filial to farmland are set up among the general public, and the Confucian thoughts of benevolence, filial piety and service are taken as the criteria for selecting officials, so as to persuade the people to respect and serve the elderly, so as to achieve the goal of developing production and stabilizing and prospering the country.
Filial piety is the core of Confucianism. Confucius thought: "Filial piety is the foundation of virtue, and teaching is born from it." In ancient times, it was the result of filial piety that "the late king had the road of supreme virtue to obey the world, make people harmonious and have no complaints from top to bottom". It is also called "filial piety is the foundation of benevolence" and "the business of a gentleman is based on morality". If a person is "filial, it is rare to be guilty; It is not easy to make mistakes, but people who are good at making trouble are not there. " I strongly advocate that "a man's trip is greater than filial piety." This kind of filial piety thought is conducive to diluting the opposition between the people and the rulers, forming a social atmosphere of respecting the old and loving the young, and consolidating the state power, which is naturally accepted and advocated by the rulers. In the first month of the fourth year of Huidi (19 1), in order to stabilize social order and encourage the development of production, the imperial edict "Anyone who shows filial piety to the people will be rehabilitated" was promulgated. Those who honor their parents, obey their brothers and work hard at farming will be exempted from the burden of lifelong tax corvee, setting an example of filial piety and diligence for the broad masses of the people. In the first year of Lv Hou's weighing system (pre-187), he began to "appoint one person to filial piety Tian 2,000 stones" among officials, and designated "filial piety Tian 2,000 stones" as the official name, with a salary of 2,000 stones, belonging to the upper-level officials, who could wear blue ribbons and silver seals, indicating that the court respected this official very much, and at any time. In the twelfth year of BC (BC 168), Emperor Wen wrote: "Filial piety is the greatest sum in the world; Tian Li is the foundation of life. Three old people, the teacher of the whole people; Honest officials are the people. Lian is very grateful for this trip to the second and third doctors.
In today's county of ten thousand households, the cloud has no order. Is it really human? It is a way for officials to recommend talents who are not prepared. He sent five people to pay tribute to the three elders, five filial people, two filial people and three honest people, and brought more than 200 stones. It is not convenient to ask the people, but the household registration rate is used to set the three old people to be filial, so that each rate can guide the people. "For filial piety, Wendi not only strongly advocated it, but also set an example and took necessary measures to supervise its implementation. Confucius said that "there must be loyalty in a city with ten rooms", and Emperor Wen of Han believed that there must be honest, filial and hard-working people in Wanjia County. They are role models of the people and should be respected and elected as officials. It was under the advocacy of Emperor Wen of Han Dynasty that Confucian ethics became popular all over the world. Although Emperor Jing did not reuse Confucianism, he still adopted Confucianism, and the Confucian thought of ruling by virtue was highly respected. The measures taken by Emperor Wen, such as "eliminating slander, eliminating corporal punishment, rewarding elders and accepting orphans", were regarded by Zhao Dezhi's dance as "the rule of virtue is generous, beneficial to the world, beneficial to the world, and unable to get happiness".
At the same time, ministers praised Jingdi for "always thinking about filial piety", and he was an emperor who ruled the world with filial piety. During the period of Emperor Wu of the Han Dynasty, with the improvement of the national situation and the change of policies, filial piety was no longer advocated. However, in order to broaden education, improve customs, recruit talents and strengthen official management, the slogan of "advocating honesty and filial piety" was put forward, and all counties and countries were ordered to recommend virtuous or filial essays, so that many Confucian scholars who had read a large number of poems and books had the opportunity to be officials and presented a prosperous scene of talented people.
