(Chinese: “flat peach”), in Chinese Taoist mythology, the peach of immortality that grew in the garden of Hsi wang mu (Xiwangmu) (“Queen Mother of the West”). When the fruit ripened every 3,000 years, the event was celebrated by a sumptuous banquet attended by the Pa Hsien (“Eight Immortals”).

Hsi wang mu presented the p'an-t'ao to favoured mortals such as the ancient Chou-dynasty emperor Mu-wang and the Han-dynasty emperor Wu-ti (141/140–87/86 BC). The first Ming-dynasty emperor (late 14th century AD) is said to have been presented with a p'an-t'ao stone identified, by 10 engraved characters, as formerly belonging to Wu-ti. Flat peaches from Chekiang province were sent each year to the imperial palace in Peking before the founding of the Chinese Republic (1911/12).
