Difference between Han Dynasty field and estate economy and Song Dynasty field and estate

What the owner wants to say should be the comparison between the Eastern Han Dynasty and the Song Dynasty, because it was in the Eastern Han Dynasty that the Han Dynasty's field and village economy took shape.

I personally think the main difference is the different degree of independence between the two. The Eastern Han itself was founded by Liu Xiu on the basis of enlisting various local magnates, so the magnates in various places owned a lot of land. In their territories, they lived together in clans with the ties of clan law, forming a large-scale, diversified and self-sufficient economic organization. In the early days of the Eastern Han Dynasty, Liu Xiu tried to limit the participation of the powerful, for example, by promulgating the Decree on the Measurement of Fields, strictly limiting the participation of the powerful in the appointment of assassins, and strictly limiting the private armament of the powerful, the "ministries". But after the Han Dynasty, the powerful have been able to develop almost without fear, and after the Yellow Turban Rebellion, the powerful have become the real rulers of the country.

The Song dynasty's farm economy was not as obviously clan-based as the Eastern Han Dynasty, and their interoperability with the outside world must have exceeded that of the Eastern Han Dynasty.
