The moment she mentioned Jiangnan, I thought of Bai Juyi's 'how can one not recall Jiangnan?'
Tips
history
Closing line of 白居易《忆江南·其一》 (Bai Juyi, Tang, c. 830s, written long after his service as governor of Hangzhou and Suzhou): 江南好,风景旧曾谙。日出江花红胜火,春来江水绿如蓝。能不忆江南 (Jiangnan is fine — its scenes long familiar. Sunrise — river flowers redder than flame; spring — river waters greener than indigo. How can one not recall Jiangnan?). The ci that fixed 江南 in Chinese letters as the country of homesick longing.
usage
Read as a rhetorical question: 'of course one remembers / how could one forget.' Each of Bai's three 《忆江南》 ci closes with this same line, forming a refrain. 忆 = 'to remember / recall,' stronger than just 想.
