After the founding of the Ming dynasty, Zhu Yuanzhang learned the lesson of the failure of Song and Yuan dynasty and reinstated the institution of appointing his twenty-three sons as princes and entitled them to build up their palace, bureaucracy, official robes, and privileges in their lands. The Ming princes did not rule local population, and they had nominal commanders of armies. They were symbolic reminiscence of ancient princes protecting the imperial court from outside threats.
- The Ming court appointed imperial sons and provided them with gold certificates and seals. But it did not issue new certificate, it only allowed them to pass gold seals to their sons, which is manifested in the wooden seal of "Prince Lu" with gold coating uncovered from the tomb of the prince.
