《汉书·传·匈奴传下》
王莽便派王歙和他的弟弟骑都尉展德侯王飒出使匈奴，祝贺单于新登大位，赏赐给黄金、衣被、缯帛，欺骗单于说他入侍的儿子登还在中原，并给钱要求单于把陈良、终带等人交给朝廷。
莽遣歙、歙弟骑都尉展德侯飒使匈奴，贺单于初立，赐黄金衣被缯帛，绐言侍子登在，因购求陈良、终带等。
Wang Mang then sent Wang She and his younger brother, the You Duwei Zhan de Hou, Wang Sa, as envoys to the Xiongnu to congratulate the Chanyu on his new throne, giving him gold, clothing, and silk, and deceiving the Chanyu that his son, Deng, who had served in the court, was still in the Central Plains. He asked for money to hand over Chen Liang, Zhong Dai and others to the imperial court.
