Nanjing also features the tomb and mausoleum of Dr.Sun Yat-Sen, the leading mind of Kuomintang and "father of modern China". Must be the only place on the mainland where the Kuomintang symbols are openly displayed out of respect for the revered Doctor.
While I don't like Shanghai style Chinese food that much and prefer f.ex Nanjing style, the Japanese and Korean restaurants in the "Japantown" and "Koreatown" of Honqgiao are as good as they come outside of the respective countries.
