Song Huizong Chongning entered a private school in Toyota Village for three years (1 103). When he was young, he was smart, studious and brilliant. According to legend, when I was twelve years old, I went to my grandfather's house with my mother and passed by Goose Beach. I met some pigs who collected land tax and robbed the poor people of their money. People cried and cried, which attracted many people to watch. I heard the woman crying and said, "My family sold a few acres of land to Master Wu last year, and this year the government wants me to pay taxes. How can I get tax without land? " How do you spend the day? "Li Chunnian after hearing this, determined to average tax in the world in the future.

After Li Chunnian entered the Jinshi, he was eager to implement tax equalization and wrote to the emperor, "requesting a change of dynasty to enrich the country and strengthen the people." Hui Zong felt out of place, coupled with civil strife and social unrest, so Li Chunnian was not appointed in time, and he lived at home. In view of the disadvantages of uneven taxation, average taxation and reasonable burden at that time, and in order to gain experience, the village name Toyota was renamed Tian Jie.

It was not until the second year of Shaoxing in the Southern Song Dynasty (1 132) that Li Chunnian became the magistrate of Ningguo County in Xuanzhou, and then moved to Ningguo Army to promote officials. During his tenure in Ningguo County, it was at the beginning of the Southern Song Dynasty and the end of the Northern Song Dynasty. The political situation is turbulent and people's hearts are unstable. He adopted the method of punishing evil and promoting good, and stabilized people's hearts in time with kindness and prestige. A great citizen used social unrest to forge land titles and forcibly occupy the fertile land of civilians. Li Chunnian learned of this situation, carefully investigated and verified the truth of the matter, ordered the return of the encroached ones, and compensated Chen for his economic losses in recent years, and instructed him to spend an hour thinking about the wall in Huaxia Pavilion (built by Fan Faxiang, the magistrate of Ningguo County in Tang Dynasty). Li Chunnian won the support and support of the villagers because he punished the bully in time. Educate villagers to live in harmony and persuade them to plant mulberry and raise silkworms. Try to pay taxes on average according to the field, that is, re-measure the land and pay taxes according to the quantity and quality of the actual field, which laid the foundation for the later implementation of the "border law". When Li Chunnian was appointed county magistrate in Ningguo, he admired Fan Faxiang, the county magistrate in Ningguo in Tang Dynasty, and influenced county officials with his words and deeds with his motto of "A husband is an official, and a servant is also a servant", thus truly realizing that "an official is a public servant of the people". During the period of Ren Ningguo County Order, "the official is clever and the people are salty."

At the beginning of the Southern Song Dynasty, Qi Fang led the suffering people to revolt, and later led them to vote for Du Chong in Jiankang. After Du Chongbing changed, his men scattered. In the third year of Jianyan (1 129), Qi Fang reorganized the skirmishers, plundered everywhere, became a thief in Jiangyang, killed Hutang, a magistrate in Zhenjiang and a comfort station in western Zhejiang, and killed the left-behind company, thus breaking the German army and surrounding Xuanzhou. Ri Kwang chon, the Song Dynasty thief, broke Ningguo County and went to Xuanzhou at the gates. It was a great headache for the Southern Song Dynasty court to become a general in both vertical and horizontal directions. In March of the fourth year of Gao Zongji, Qi Fang was trapped in the Guangzhou German Army, and Wang Tao was sentenced to death. In April, Qi surrounded Xuanzhou, and from Guangde to Xuanzhou, Ningguo was ravaged by it. Needless to say. In May of the year of Jian 'an (1 130), Kouningguo, Fangkengkou (now Fangjiachong in Panlong Village of Ningguo Municipal Office, which has now become the flooded area of Qinglongwan Reservoir), and Fang Zhiyao led the township soldiers to Fushiling Pass (now Shanmen East, in front of the gate of Tianxiamu Village, formerly known as Shiling). Fang Zhiyao led the troops in pursuit and assassinated his white horse general in the mud. Qi magnified his anger and laid siege to Fang Zhiyao. Zhi Yao's arrow was captured, and Qi Fang coerced him to surrender. Zhi Yao scolded: "Am I following the thief?" The thief broke his head and left.

In the fourth year of Shaoxing (1 134), Li Chunnian, the county magistrate, learned that Fang Zhiyao, a Yi people, had devoted himself to defending the court of the Song Dynasty and keeping the local people safe. In order to praise Fang Zhiyao's loyalty, he made a special wish to sacrifice to death and reported the matter to the court. Song Gaozong posthumous title named him "Yilie" and set up a temple to worship him, named "Yilie Gong Fang Temple", and combined the book "Yilie Yong Fang is the barrier of Ningchuan; Justice is clear and is the rule to protect the future. "

During his tenure in Ningguo County, Li Chunnian was honest and clean, loved the people and loved the people, and was well received by the people. In the lobby of Yiren County, a plaque of "Xichun Hall" was presented, praising him for shining Ningguo like the sun and giving people the warmth of spring. During the Jiajing period of the Ming Dynasty, the plaque in the lobby was also called "Xichun".

In the fifth year of Shaoxing (1 135), in April of the summer calendar, Liu Dazhong, an official from the eastern and western parts of the south of the Yangtze River, came to inspect and assess state and county officials. After an unannounced visit to Ningguo County, I found that Li Chunnian was honest and upright, with outstanding achievements, and was deeply loved by the people of the county. So, I recommended Zhao Gou to Emperor Gaozong, saying that he was "diligent, tax-checking, and organized, so please reuse him". In May, Song Gaozong summoned Li Chunnian and asked about the interests of the people.

Li Chunnian replied: "The state and county are dead, and there is no room for one person; Summer and autumn taxes will be handled slightly at your own expense. " He was promoted to Hongzhou (now Nanchang) as a judge because he didn't sing praises for the holy family and spoke honestly and frankly.

In his later career, Li Chunnian was determined to get rid of the disadvantages of the times and deal with the economic circles in accordance with Mencius' political proposition that "benevolent governance starts from the economic circles". Li Chunnian led officials from the Ministry of Housing and Urban-Rural Development, such as Cang Langwang, to Pingjiang Prefecture (now Suzhou) to carry out the pilot project of economic circle. He presided over the capital as a unit, and ordered official households and private households to write the name of the head of the household, the area of the field, four directions, the soil color, the cross section of the mound and the source (business or ancestral property) according to the formula, and attached a map of the field. Then measure, take five feet square as a step, sixty steps as a corner, and four corners as an acre, and calculate the acre angle. Then register the owner's name, population, field quantity, quality, tax, etc. And establish the "anvil base". It took five months to get back to Beijing. Emperor Gaozong saw the "thin anvil base" which combined household registration, cadastre and tax registration, and realized that "the people have fixed property, fixed property tax and fixed tax levy". It is very clear that land owners pay taxes through registration and the government pays taxes through thin tax. Emperor Gaozong was very happy, and immediately promoted Li Chunnian to assistant minister, so that he formulated the Law of Realm. According to the pilot experience, Li Chunnian wrote 24 "State Law". Emperor Gaozong issued another imperial edict, pushing the "Clear Boundary Law" to the whole country. If an official breaks or obstructs the law of clear boundaries, he will be sentenced to imprisonment. The Economic and Trade Office was renamed as the Economic and Trade Bureau of the Ministry of Housing, which gave unified guidance and management to the land and taxation of the whole country, and audited the economic and trade files of various prefectures (prefectures, armies and prisons) and counties. States and counties also set up economic border bureaus or offices, which are directly under the jurisdiction of the Economic Border Bureau of the Ministry of Housing.

The "Economic Border Law" is being implemented intensively throughout the country. In areas where the "Cross-border Law" has been well implemented, hidden fields and households have been found out, achieving the goal of tax equalization with remarkable results. It has stabilized people's livelihood, developed production and eased class contradictions to varying degrees. It has the support of farmers and small landlords, as well as some honest officials. But it violated the personal interests of big landlords and some bureaucrats, and they rallied to attack Li Chunnian. One morning in the 19th year of Shaoxing (1 149), just as Li Chunnian summarized and reported the implementation of the Jingjie Law, before he finished, Qin Gui was afraid that his plot to tamper with the Jingjie Law, falsely spread imperial edicts and secretly increase taxes on the people would be exposed, and immediately instructed Cao Jun, an imperial envoy in the confidant temple, to impeach Li Chunnian and recommend Liu Dazhong. Now that the boundary has been fixed, if the official is not sent back to the real person, the general will marry privately the next year, and the crime of protecting his family will be unstoppable. "In order to quell public anger, Song Gaozong" lost his original intention ",which means that he didn't do what he intended, but just dismissed his official. But this does not deny the "realm law".

From then on, he was demoted to Jiangzhou (now Jiujiang) and Xuanzhou until the 24th year of Shaoxing (1 154), that is, the first month of Qin Gui's death, which was designated as Xuanzhou year. Zhu, who was studying at Ziyang College in Shexian at that time, respected Li Chunnian's moral knowledge and often went to Xuanzhou for advice. They share the same interests. At the age of fifty-nine, Zhu, 34 years younger than him, became a "forgotten friend" and he had a great influence on Zhu. Later, when Zhu was the magistrate in Zhangzhou, he wrote many letters to Xiao Zong and Guang Zong, demanding that Zhangzhou, Quanzhou and Tingzhou implement the "Jing Jie Law", which inherited and developed Li Chunnian's career.

In the 25th year of Shaoxing (1 155), in the first month, Li Chunnian became a doctor of Zuozhong, and he knew Wuzhou (now Jinhua). In order to encourage local farmers to develop production, he followed the example of Sang Hongyang in the Western Han Dynasty and Wang Anshi in the Northern Song Dynasty, and established "Pingyi". Lending the surplus government money to farmers at the interest rate of two cents effectively curbed usury; And under the principle of voluntariness, the unified purchase and marketing of agricultural and sideline products is implemented, which effectively inhibits wealthy businessmen and wealthy households from hoarding and driving up prices. Organize farmers to process agricultural and sideline products, set up farmers' offices, and raise pigs and sheep that can't be sold that day. It was a move that benefited the country and the people, but it violated the personal interests of wealthy businessmen and rich people. It was impeached by Ling Zhe, the right official of the imperial court, and called it "Pingwu". In fact, he tried his best to get a loan from a county, usurped the interests of the people, and then borrowed official money from the people every day to reap its benefits, but Li Chunnian was not involved in seeking personal gain from it. Emperor Gaozong only listened to one side of the story, and Shaoxing was dismissed for twenty-six years (1 156).

At the age of 60, he returned to his hometown to set up Xintian Academy, taught rural children, devoted himself to study, wrote books, and published them with Yi Jie and Doubt. In the second year of Longxing in Song Xiaozong (1 164), Li Chunnian died at home at the age of 68.

Li Chunnian was loyal to the monarch and patriotic all his life, diligent in political affairs, frugal in life, determined to reform, fearless of power and devoted himself to the economic circle. He made great contributions to the ancient tax system reform and became a financial expert in the Southern Song Dynasty.
