Due to the emptiness of the Song Dynasty's treasury, there was no way to increase the price of rice, and the only feasible thing was to rely on the issuance of paper money. The massive issuance of banknotes caused a serious depreciation of the currency. Just when Jia Nidao was overwhelmed by the problems of construction, peace, and military salary supply, Liu Lianggui, who knew Lin'an Mansion, and Wu Shiqing, the transshipment envoy of western Zhejiang, successively offered him the policy of buying back more than the limit of land as public land, and soon won Jia Nidao's approval. Under the instruction of Jia Yidao, the palace attendant Chen Yaodao, the right Zhengyan Cao Xiaoqing, the supervisor Yu Yu and Zhang Yanyan asked for the implementation of the public land law, and they said: "The law of limiting the field has existed since the past. If the official household exceeds the limit of land, it will be strictly returned and flown away. If you buy back the official land, you can get 10 million mu, and there will be 6 or 7 million stones per year, which will be more than enough for military salaries. You can be exempted from peace, you can live in disadvantages, you can pay the army, you can level the price, and you can get rich. One thing and five benefits are infinitely beneficial. ”

The "five benefits" mentioned here, if implemented properly, are indeed not empty words, in addition, there are still benefits that can be mitigated by land annexation, in order to prevent the rebound from being too large, the music is deliberately not stated.

However, the implementation of the "Public Land Law" directly affected the vital interests of many bureaucratic landlords, and the "Ke'an Fu Room" was only in terms of mitigating the excessively heavy peace, and as for the purchase of land that exceeded the limit at a low price, it was simply painful for them to rip off their flesh, and they were bound to violently oppose it. Therefore, at the beginning, the emperor couldn't help but hesitate, and only made an internal approval of "Ran Dong is Fang Xing, the right is in the autumn, and the implementation of the proposal will be continued", in order to delay time. The emperor had to issue an edict again to affirm the "good law and good intentions" of the "Gongtian Law", and decided to try it out in the six prefectures of western Zhejiang, including Pingjiang (Suzhou, Jiangsu), Jiaxing (now Zhejiang), Anji (Huzhou, Zhejiang), Changzhou, Zhenjiang, and Jiangyin, which have the highest grain output, and then promote other roads. In order to set an example, Jia Rudao took the lead in offering 10,000 acres of Zhejiang West Tian as public land, and Zhao Yurui, the king of Rong, and Zhao Mengkui of the Zhejiang West Sect all contributed or sold one after another.

Jia Rudao implemented the public land law, took the lead in donating his own land, and wanted to do one thing to prosper the five benefits, so as to save the social crisis and realize the prosperity of the country and the strengthening of the army, and his subjective desire was entirely for the fundamental interests of the Song Dynasty regime, and at the same time, the interests of tenant farmers were also taken into account in the collection of public land rent. Although it is actually a partial expropriation of part of the land of the bureaucrats and landlords, and there are some shortcomings in its implementation, it is obviously not linked to the "cruel policy of economic plunder."

Sun Hui knew that Jia Yidao and others had given serious consideration to the implementation of the "Public Land Law". First of all, from a regional point of view, it chose the six counties in western Zhejiang, which were rich in grain and had been known as "Suhu ripe and the world was full" at that time, as a pilot, rather than rushing up. Second, the implementation of the rules and regulations is relatively strict: for example, the starting point for buying back land that exceeds the limit is not low, even if it is later reduced to 100 mu, it is still limited to the homes of small and medium-sized landlords, which is far higher than the starting point of 30 mu proposed by Ye Shi, and basically has no impact on the vast number of landless and landless peasants. Third, there is a complete set of management methods and a system of rewards and punishments for public land, and due consideration is given to the interests of farmers who rent public land, and the amount of rent set is far lighter than that of private land. Therefore, as far as the public land law itself is concerned, it is beneficial to the state and does not increase the burden on the vast number of peasants, and the advantages outweigh the disadvantages.

The "Public Land Law" was implemented for a total of 12 years, which not only ensured the supply of military salaries, but also played a considerable role in reducing the number of peacemakers, reducing the issuance of paper money, and stabilizing grain prices. However, the scholars of the time turned a blind eye to these achievements out of class prejudice and personal self-interest, exaggerated the drawbacks, and blindly attacked them.

The implementation of the "Public Land Law" first had to merge the land of the people under false pretenses, and secondly, to buy back the land that had exceeded the limit, both of which seriously harmed the vital interests of the bureaucrats and landlords, so they were strongly opposed from the very beginning. One year, when a comet appeared, the emperor issued an edict asking Chinese and foreign ministers to say that the government was in a state of failure, and many officials took the opportunity to ask for the abolition of the "Gongtian Law" in response to the changes in the sky. They accused the "Public Land Law" of "pursuing too much, restricting the name of land, changing it into a merger of households, and then changing into a change of land, the cultivator is unemployed and displaced, and the landlord is innocent and restrained, and the reason why this demon comet has changed slightly." "Gongtian Faqiang buys people's land, and it is a disaster for Zhejiang, and there is no rich family in Zhejiang Road since today." , "Seize the people's land in vain, poison several counties, sue and discard, and do not sell a penny." So everyone was broken, the small people were helpless, the price of rice soared, and they starved to death", and claimed that "those who know it say that there is chaos in western Zhejiang on a different day, and it will start from the public field." Although the opponents have imposed many charges on the Public Land Law, the most important one is that they forcibly bought the land of "landlords", "rich families", and "big families", which seriously damaged their interests.

Opponents know that the success of the "Public Land Law" in the six counties of western Zhejiang is likely to be extended throughout the country, so that all bureaucrats and landlords will be deprived of their land in disguise, and the degree of damage will far exceed that of the previous economic boundaries and land restrictions. Therefore, the "Gongtian Law" was like a fierce beast for the entire bureaucratic and landlord class in the Song Dynasty, and it is completely conceivable that their opposition to the "Gongtian Law" was fierce.

In addition, the rule of officials in the Song Dynasty was very corrupt, and any decrees and measures promulgated by the imperial court, through the hands of these officials, could not be correctly implemented, even if they were "good laws and good intentions", and would eventually become bad laws and harm the people. The implementation of the Public Land Law is no exception.

After Jia Nidao implemented the "Gongtian Law", he offended the ministers of the court, especially the Jiangnan landlord class, and they left Jia Nidao one after another, making him fall into an extremely isolated situation.

The purpose of Jia Yidao's implementation of the "Public Land Law" was not for personal gain, but to save the social crisis, and he himself paid a heavy price for this. If Sun Hui hadn't reversed the outcome of the Battle of Xiangfan in time, he would probably have lost his life as in history.

And Sun Hui learned the lesson of Jia Nidao's blood and tears in implementing the "Gongtian Law", so this time the method he adopted was not to use his huge power to "drive out or make up for the outside" with his huge power, forcing them to "dare not speak out and dare to be angry", so that the "Gongtian Law" was reluctantly implemented, but to let those opponents enter the pit themselves.

As the "leader" who led the "flock" into the pit, Rongwang Zhao Yurui was the best choice.

With the help of Qin Yu, Sun Hui's goal was successfully realized. What is commendable is that his knife can be said to have slashed at King Rong's body, but King Rong not only did not feel pain, but felt very comfortable.
