ist wohl eine Frage der persönlichen Interessen, ich habe eine ähnlich lange Leerlaufzeit mal mit einem Rundgang über Shamian Island (mit U-Bahn Linie 1 schnell zu erreichen), einem Besuch des westlich angrenzenden Fischmarktes und einer kleinen Tour per Fähre nach Fangcun und zurück verbracht.
Da Du Dich offenbar für Verkehr interessierst (schliesse ich aus dem Interesse an der Bahn), könnte eventuell auch eine Fahrt mit der neuen Bus Rapid Transit Linie (letzte Woche mit einigen Anlaufschwierigkeiten eröffnet) interessant sein?
zu Shamian Island noch kurz der Ausschnitt von travelchinaguide:
Shamian Island has great historic significance. From the Song and the Qing Dynasty, Shamian Island served as an important port for Guangzhou's foreign trade. Shamian became a strategic point for city defense during the second Opium Wars (1856-1860). In 1859, the territory was divided into two concessions, given to France and United Kingdom (of which 4/5 belonged t the British and 1/5 belonged to the French). It was then embanked and provided with streets, drainage, and imposing buildings and became home to a prosperous foreign enclave. From the late 1800s to the early 1900s, most of the public facilities were finished, including political buildings like consulates, cultural buildings like churches and schools, as well as commercial buildings like banks and firms. After 1949, the mansions of Shamian became government offices or apartment houses and the churches were turned into factories. But later they were restored, in many cases to their former splendor, with each building labeled as to its former purpose. One may start to imagine the stories staged in the building while seeing the plaque writing about its previous function, like "No.7 North Shamian Avenue" (Built during the Republican period, formerly the Administration Bureau of Broadcasting of the Nationalist Government). The mansions in Shamian form the best preserved Western Europe style building complex in China. Forty-two out of 150 buildings are counted as the most exotic ones, Gothic, Baroque, and Neoclassical, in Guangzhou.

Shamian is good place for stroll. As it is just 900m long from east to west and 300m from south to north, one will not feel tired even after walking around the island twice. Dues to traffic control on the island, Shamian showcase a different atmosphere and living pace. No such problems as traffic jam and exhaust gas pollution exist here. Now partly pedestrianized, its broad boulevards are like long thin gardens with a lot of topiary. A line of bars and cafes on the southwest side with views over the Pearl River serves modern expats.
