This term has two meanings. One is a grand sacrificial ceremony held in ancient times by an emperor after ascending to the top of Mount Taishan to pay tribute to heaven and earth, announce his achievements, thank gods for having brought him and his people good fortune, and inscribe his achievements on a huge stone. He performed this ceremony to declare to the world that his power was bestowed by Heaven. A heaven-worshipping ceremony was held on an earthen terrace on the top of Mount Taishan. An earth-worshipping ceremony was held on a clearing on the Liangfu or the
Yunyun Hill near Mount Taishan. According to legend, the Three Sovereigns and the Five Emperors, hero Yu who brought floods under control, King Tang of the Shang Dynasty, King Wu of the Zhou Dynasty (?-1043 BC) all held such ceremonies during their reigns. After the founding of the Qin Dynasty, only the First Emperor of Qin (259-210 BC), Emperor Wu of the Western Han Dynasty (156-87 BC), and Emperor Guangwu of the Eastern Han Dynasty (5 BC-AD 57) held such ceremonies on Mount Taishan.
The other meaning of this term is an ode
composed to urge the emperor to hold such a sacrificial ceremony or to record
its actual process if a sacrificial ceremony was held to extol his
achievements. Such an ode was first written by Sima Xiangru (179?-118 BC) of
the Western Han Dynasty. Liu Xie (465?-520) of the Southern Dynasties held that
the ode, as a declaration of royal achievement in its era, should be solemn, grand,
factual, eloquent and graceful. To extol an emperor's greatness and the
miraculous power of heaven and earth, the author should select old yet lucid
words from the classics, or use new words rich in implication. He should give
free rein to his imagination. Sacrificial odes later became standard
commemorative speeches. Liu Xie's requirements, when observed, may help boost
the image or morale of a company, a governmental or cultural institution, a
region or even the whole country. Good ceremonial speeches, poems or essays can
become representative writings of a particular era.
