Does the big landlord grange in the Eastern Han Dynasty refer to the powerful landlord grange?

I think the big landlord grange and the big landlord grange belong to the same concept. The so-called big landlord grange, different from the general landlord manor, means that it reached a certain level and had a stronger influence on the politics and economy at that time-economically occupying a large number of land and farmers, affecting the national tax revenue, and the manor was self-sufficient; Politically, it shows a trend of separatism. This is a concept with the tyrannical landlord grange.
