In the first lunar month of the second year of the Deyou era (1277 by the Julian Calendar), the Mongol Army arrived at Nieiting Mountain (臬亭山), in the northern suburbs of modern-day Hangzhou, Zhejiang Province. On the 18th of the same month, Dowager Empress Xie sent minister Yang Yingkui (杨应奎) into the Mongol army camp to surrender and offer up the Imperial Seal. The soon to be Yuan Dynasty leaders requested talks with Prime Minister Chen but that night he fled to Lin'an (modern day Hangzhou) then later to Wenzhou in the south east. During November 1276, the first year of Emperor Duanzong of Song's Jingyan 景炎 Era, the Mongol army entered Fuzhou in Fujian Province and the government surrendered. Chen and Zhang Shijie accompanied Emperor Duanzong to the sea when not long afterwards Chen again fled. By the time of the destruction of the Southern Song Dynasty, Chen had already taken his wife and children to Champa (in modern-day Vietnam).
