Zhang Qing's father was even a hidden famous doctor, a marvel of his time some twenty or thirty years ago with the reputation of a "Divine Doctor." He later retired and disappeared without a trace, which were all findings from Cao De's investigation.
The Huang family had an excellent family tradition. Huang Zude's father was an upright and uninterested-in-fame individual who devoted himself to the medical craft and saving lives. It was rumored that this Divine Doctor retired because he was forced by others, unwilling to be corrupted, and hence withdrew from the sight of those in centers of power and the nobility.
To train Huang Zude's medical skills, the Divine Doctor often took him out since he was a child, practicing medicine and saving lives in the streets like an itinerant doctor, covering Baoding Mansion, Yanqing Mansion, and Kaifeng County.
