《幼学琼林·卷一·文臣》
藩垣、屏翰称镇守一方的长官，如同方伯是古代诸侯国的长官一样；墨色的绶、铜铸的章就是县令所用的，县令的辖境类似古代子爵、男爵的小邦。
藩垣屏翰，方伯犹古诸侯之国；墨绶铜章，令尹即古子男之帮。
The governor of one side is called Fanyuan / screen, just like the governor of the ancient vassal state; the black mark and bronze seal are used by the county magistrate, and the jurisdiction of the county magistrate is similar to the small kingdom of the ancient viscount and baron.
