sole empress. Also in spring 573, Zu Ting, knowing that Gao Wei had a love of literature, with Gao Wei's approval, established the Wenlin Hall (文林館), headed by the officials Li Delin and Yan Zhitui (顏之推). They retained a group of literarily-capable men and authored one of the great compendia of the era, the Xiuwendian Yulan (修文殿御覽). In summer 573, rival Emperor Xuan of Chen launched a major attack across the Yangtze River, commanded by the general Wu Mingche. Gao Wei went against the advice of the officials Wang Hong (王紘), who advocated passive resistance while reducing tax burdens to strengthen the people's resolve, and Zhao Yanshen, who advocated commissioning the Liang Dynasty general Wang Lin, who had long wanted to reestablish Liang at Chen's expense, with an army. Rather, Gao Wei sent reinforcements to the attacked provinces—but only in small amounts, not sufficient to resist Chen forces—with the main force commanded by Wei Pohu (尉破胡) and Zhangsun Honglüe (長孫洪略) defeated by Wu's troops. Wang, who accompanied Wei as a consultant, was then ordered to go to Shouyang (壽陽, in modern Lu'an, Anhui) to defend that city against attack—but with severe limitations on his authority. Soon, Shouyang fell, and Wang was captured and executed by Wu. All of Northern Qi's territory between the Yangtze and the Huai River fell into Chen control. Despite the losses, however, Mu Tipo and Han advocated continued epicurean lifestyle on Gao Wei's and their own parts, with Mu famously stating, "Even if we lost all territory south of the Yellow River, we can still be like Qiuzi (龜茲, a city state in modern Xinjiang). But what is more piteous is that a human life is like borrowed time, and we should use all this short period to seek pleasure. Why worry about Shouyang?" Gao Wei agreed, and continued to spend his days feasting. During the Chen attack, Zu, who had become embroiled in conflict with Lady Lu, Mu Tipo, and Han, was expelled from the central government over his attempt to impose a reform regime to streamline the government and reduce expenses. He would not return, and after his departure, the government became even more inefficient than before. Further, also during the campaign, Gao Wei became suspicious of his cousin Gao Changgong (高長恭) the Prince of Lanling, a capable general, and poisoned Gao Changgong to death. Also during the Chen attack, another major wrongful massacre
