The Yuanjing clan possessed a unique and important heritage, so their elders took great care in planning marriages for the younger members, especially the talented ones. They aimed to keep their special bloodline pure and strong by arranging marriages within the clan, even if it meant marrying distant relatives.
A long time ago, some family members started their own branches but still maintained close ties with the Yuanjing clan and followed the same marriage traditions to keep the bloodline pure. Despite these branches developing their own identities over time, detailed family records helped organize marriages between descendants of those who branched out from the Yuanjing family many generations ago. This careful planning ensured the Yuanjing bloodline remained exclusive and uncontaminated by outside influences.
