I lived in Beijing for nearly three years, and met some writers who, after 50 years under communist rule, still considered themselves the "source" of culture and Hong Kong as merely a "downstream" offshoot. Indeed, some didn't even deign to consider Hong Kong as "downstream," but saw it as a barren cultural desert.
我在北京住了近三年，也知道部分京派文人經過五十年共產統治，仍高高在上自認為是「源」，而香港是「流」，說穿了，根本連「流」的資格也沒有，根本是文化沙漠。
