Wu Zi Bei Ge

Wu Zi Bei Ge (无字碑歌), also known as Wu Zi Bei Ge: Wu Zetian Zhuan (无字碑歌：武则天传), is a 2006 Chinese historical television series based on the life of Wu Zetian, the only female emperor in Chinese history. Directed and written by Chen Yanmin, the series starred Siqin Gaowa as Wu Zetian. Its Chinese title means "song of the uncharactered stele", a reference to the unmarked stele near Wu Zetian's tomb at the Qianling Mausoleum in present-day Qian County, Shaanxi.
