Well-field system is that the king of Zhou enfeoffed the vassal land and people, the vassal enfeoffed the doctor and the doctor enfeoffed the scholar. These lands are registered, and although they are not taxed, they still have to be paid. However, private newly developed fields will not be catalogued, and the appearance of these newly developed fields has greatly affected the well site system itself. On the other hand, the Jing Tian system was used to maintain the power of the Zhou Emperor under the hierarchical system. The emergence of a large number of new fields greatly enhanced the strength of princes for two reasons: the output increased and tribute was not paid. Financial resources are gradually abundant; In order to maintain the newly developed land and continue to develop land, it is bound to encourage fertility, make the population surge and increase military strength.

As a result, the strength of the vassals increased, and the strength of Zhou Wang gradually weakened. The system established with the authority of Zhou Tianzi had to withdraw from the historical stage.

take for example

When there were no iron plows in Niu Geng, it took one day to cultivate an acre of land. Because of the appearance of Niu Geng, it only takes half a day to plow an acre of land. However, when the Jing Tian system appeared, the Zhou Dynasty was still a slave society. Slaves are not free and slave owners are inhuman. The remaining half a day, of course, the slave owners will not let their efforts do nothing, so what should we do? These people can only plow fields and can't do other crafts. Then we have to open up new land in Niu Geng with iron plows! So all over the country, there are many newly developed lands.
