"The separation of divine position and authority is indeed a good idea." Pei Xuanjing nodded in approval.
He made a suggestion: "But these ninth-grade Enfeoffments can win over countless officials, but what about those junior officials?"
The so-called officials, both high ranking and junior ones, are not the same. Officials can be promoted, but many of those junior officials spend their entire lives stuck in one place. They carry out much of the important work of supporting the administration, and their roles are often passed down through generations.
This would have been acceptable before, as even if promoted, everyone was mortal, eventually facing death, so there was at least fairness in regard to life.
