Zheng Imperial House

The Zheng Imperial House is the ruling family, surnamed He (何), which rules over the Zheng Empire. As of the 13th year of Chengyuan, it has produced 8 Emperors (and 2 deposed rulers), over 85 years.

Names
Within the Zheng Empire, the Imperial House is most commonly known simply as the Heavenly House (天家).

Records
Given the importance of correctly identifying who is and is not of the Imperial House, a centralised record - known as the Jade Registry (玉牒) - is kept which records all the members of the different branches of the House. By practice, this record is formally edited and expanded every 7 years.
