Sīmǎ Xiàngrú 司馬相如 (c. 179 – 117 BCE), zì Chángqīng 長卿, was the foremost rhapsodist (fù 賦 writer) of the Western Hàn court of Emperor Wǔ. His Zǐxū fù 子虛賦 and Shànglín fù 上林賦 set the canonical model of the courtly hunting rhapsody and established the fù as the principal genre of imperial-praise literature. The kèzhǔ 客主 (host-and-guest) dialogue device — invoked by 黃元御 Huáng Yuányù in the Sùlíng wēiyùn (KR3ea053) — is the structural signature of the Zǐxū / Shànglín pair.
