The Chinese newspaper, The People's Daily (English, Web, edition) has images of a dying 800 year old village, that illustrates some trends and problems in modern China. It is not typical of all the problems causing urbanisation in China, but does illustrate some.
The village is Dacan ancient village, located in Yuxian, in north China's Shanxi Province. It is surrounded by mountains. And the first image I've selected illustrates the access to the village:
This is typical of the landscape and its where the Chinese Communist Party took refuge (at the end of the fabled 'Long March.'), after being driven out of south China by Jiang Jie-shi (Chiang Kai-shek), after the death of Sun Yat-sen, who had brought the then small CPC into his larget Guomendang (KMT).
After the 1937 invasion of China by Japan, this is the area where the communists were able to fight a guerilla war against the Japanese. A struggle that was likely more passionate and successful than the anti-japanese war fought by Jiang Jie-shi, and his Guomendang. American General, Joe Stillwell, who was the American C.O. in East Asia called Jiang a 'peanut' and accused him of being afraid to fight the Japanese, and in contrast ultimately praising the Communist war effort.
But you can see (from this pik) why the Japanese found it difficult to penetrate the mountainous terrain in which the communists took refuge.
But that was then. Now such villages are dying. The PD article states:
Eight years ago, there were 85 households and more than 320 villagers, but now there are only 11 households and 17 residents, with the oldest being 90 years old and the youngest 50 years old.
