Princess Taiping
It is not known when Princess Taiping was born, but it is known that she was the youngest of the six known children of Emperor Gaozong and his second wife Empress Wu (later known as Wu Zetian). In 670, when Empress Wu's mother Lady Yang died, Empress Wu had Princess Taiping become a Taoist nun to gain divine favor on behalf of Lady Yang. During the Yifeng era (676-679), when Emperor Gaozong was negotiating a peace treaty with Tufan, the king of Tufan requested to marry Princess Taiping, Emperor Gaozong declined — and, as an excuse, built a Taoist temple named Taiping Temple (太平觀) and commissioned her as the abbess of the temple.
