Curse of the Golden Flower is also set in the Tang Dynasty. Zhang Yimou, the director of both movies, has such a colorful way of capturing how this period might have been:
Oh, I just thought of another movie that might be during the Tang Dynasty. I researched, and yes, Mulan, may be set during the Tang Dynasty. It's unclear because Han clothing influenced clothing after, but Mulan's makeup suggests she's from the Tang. The original poem, "The Ballad of Mulan," appears as early as a century BEFORE the Tang dynasty and is expanded into a novel during the Ming.
I love fashion, even if it's centuries old.
