斛律光
In 561, another older brother of Gao Zhan, Emperor Xiaozhao, died, leaving instructions for the throne to be passed to Gao Zhan. Gao Zhan therefore took the throne (as Emperor Wucheng). In 562, he created his wife Princess Hu empress and created Gao Wei crown prince. While Gao Wei was crown prince, he married the daughter of the key general Hulü Guang as his wife and crown princess.
