Life in Guangzhou differs from life in Changsha mostly insofar as the city is far more developed and decently more cosmopolitan in outlook. I have begun studying Cantonese in order to better take advantage of my surroundings, but in truth the extent to which one needs it in addition to Mandarin is scarcely larger than the extent to which knowledge of the Hunanese dialect would have been necessary last year. A more noticeable difference - one which few Chinese people neglect to point out - is the paucity of spice in local cuisine. The regional cuisines (primarily Cantonese and Chaozhou) are notoriously bland, although in my opinion the availability of high quality dim sum makes up for the deficiency. Perhaps the greatest lifestyle improvement has been Guangzhou's ever-expanding metro system: from what I could gather, most Changsha bus drivers honed their skills on the job, and I do not miss them.
In nine days I will embark on another winter's journey along various tendrils of the Chinese diaspora, which I will surely tell you about. Until then, I recommend this level-headed, non-hysterical treatment of China's political landscape.
