Princess Qianjin was born to Yuwen Zhao, Prince of Zhao, the seventh son of
Yuwen Tai. In 579,
Taspar Qaghan hoped to ally with the
Northern Zhou through marriage.
Emperor Xuan sent Taspar his cousin Princess Qianjin in return for a Northern Qi prince, an enemy of the Zhou who had taken refuge among the
Göktürks. Taspar and Qianjin married after the traditional nomadic continual marriage. Later that year, the
Northern Zhou were defeated and the
Sui dynasty was established. In response to this, Qianjin wrote to
Emperor Wen, expressing her submission as a preliminary act of outreach. Qianjin went on to provide the Sui with diplomatic advice, urging them not to request ritual indications of Ishbara's status as a son-in-law. Although Tulan also requested a Sui wife, he was denied. == References ==
