In his essay “The
Peach Blossom Spring,” Tao Yuanming
(365 or 372 or 376-427) of the Jin Dynasty describes an idyllic place of
natural beauty, cut off from the outside world and far from the ravages of war,
free from political oppression, where people live in
equality, freedom, harmony, peace and happiness. Later, the expression came to
mean an imagined ideal society or place; also a refuge, away from material
temptations where one could live in seclusion and tranquility.
