《汉书·传·扬雄传上》
虽然把上林苑的三个边割了不少给平民，然而羽猎田车战马器械储备宫墙的建制，仍太奢侈浮华，不是尧、舜、成汤、文王三驱的本意。
虽颇割其三垂以赡齐民，然至羽猎、田车、戎马、器械、储偫、禁御所营，尚泰奢丽夸诩，非尧、舜、成汤、文王三驱之意也。
Although three sides of the Shanglin garden were finally cut away and given to the common people, the hunting grounds, chariots, horses, weapons and equipment of the palace, and the building of the palace walls were still too extravagant, and not in accordance with the intentions of Yao, Shun, Cheng Tang and King Wen in driving out the hunted animals.
