The National Teacher of Western Wei was the last royal family member of the Western Wei dynasty to serve in this role after the unification of the previous dynasty. He died under unclear circumstances, with rumors attributing his death to the royal family and noble families of the time. His death marked the point where the Western Wei royal bloodline in the court completely disappeared, though it did not become extinct. The National Teacher left behind handwritten letters that are still held by certain noble families, including the Deng family. His death is connected to the grudges that the cat tribe medical bloodline accumulated, and his lineage continues through descendants like Kang Li who still seek revenge or justice for his death. He is believed to be Kang Lis grandfather or great-grandfather.
