Tongzhi Emperor
Since the very beginning of his marriage, the Tongzhi Emperor proceeded to spend most of his time with his empress at the expense of his four concubines, including the Imperial Noble Consort Shushen, who was Cixi's preferred candidate for the Tongzhi Emperor's empress consort. As hostility grew between Cixi and the Jiashun Empress, Cixi suggested the couple spend more time on studies and spied on the Tongzhi Emperor using palace eunuchs. After her warning was ignored, Cixi ordered the couple to separate, and the Tongzhi Emperor purportedly spent several months following Cixi's order in isolation at Qianqing Palace.
