《后汉书·本纪·皇后纪上》
这时，四方诸侯之国，贡献方物，争求得珍贵华丽之物，自邓皇后即位，一律禁绝，岁时季节只要供给纸墨就行了。
是时，方国贡献，竞求珍丽之物，自后即位，悉令禁绝，岁时但供纸墨而已。
At that time, feudal states from all directions brought tribute, vying with each other to obtain rare and luxurious items. From the moment Empress Deng ascended to the throne, this was strictly forbidden. She only required paper and ink to be supplied seasonally.
