This TV play is from the Ming Dynasty. Isn't the emperor's name Zhu Jun? Think about it and you'll know it's the Ming Dynasty. The Taiwan Province version of Princess Huaiyu seems to be based on the same story, but it belongs to the Qing Dynasty, and there seems to be no related story in history. It should be fictional ~

The emperor played by Alec Su belongs to the Ming Dynasty.

Yuan dynasty was destroyed by Zhu Yuanzhang of Ming dynasty ~ ~

So the unruly princess in the play wants to restore the country ~
