The “Tale of the Peach-Blossom Land” (Chinese: 桃花源記; pinyin: Taohuayuan Ji) is set during the reign of Emperor Xiaowu of the Eastern Jin Dynasty. It tells the story of a fisherman who discovers a secluded valley (Shi Wai Tao Yuan) located on the other side of a narrow cave. The inhabitants of the valley were the descendants of war refugees from the times of the Qin Dynasty. They had lived in this utopia untroubled by the further course of history in peace and harmony ever since. The fisherman returned home to tell the story, but the idyllic valley could never be found again.
The Long Corridor (simplified Chinese: 长廊; traditional Chinese: 長廊; pinyin: Cháng Láng) is a covered walkway in the Summer Palace in Beijing, China. First erected in the middle of the 18th century, it is famous for its length (728 m) and its many richly painted murals (more than 14,000 paintings).
