Tengwang Ge Xu (Chinese: 滕王閣序; pinyin: Téngwáng Gé Xù, Preface to the Prince Teng's Pavilion), full name Preface to a Farewell Feast Atop the Prince Teng's Pavilion in Autumn (Chinese: 秋日登洪府滕王閣餞別序; pinyin: Qiūrì Dēng Hóng Fǔ Téngwáng Gé Jiànbié Xù) or Preface to Poems on the Prince of Teng's Pavilion (Chinese: 滕王閣詩序; pinyin: Téngwáng Gé Shī Xù), is a piece of literature by Wang Bo of the Tang dynasty.
It is classified as Pianwen (Chinese: 駢文; pinyin: Piánwén), which depends greatly on rhythm, somewhat like classical Chinese poetry, but does not have a restriction of how many characters should be in one sentence, and how many sentences in one paragraph.
It is named after Pavilion of Prince Teng, a pavilion standing by the Gan River of Nanchang City, which was then called Hongzhou (Chinese: 洪州; pinyin: Hóngzhou) and is the capital of the current province of Jiangxi.
Wáng Bó was on his way to Jiaozhi County, in present-day northern Vietnam, visiting his father, and encountered a grand banquet held there.
In fact, he was drowned in the South China Sea not long after he finished this classic before he reached Vietnam to see his father.
