《北史·列传·卷二十七》
先是被汲郡太守翟嵩弹劾，说他的从兄毕僧明拖欠官债。僧明原先任京城地区的长史，不受翟嵩的统属，限时命僧明还债，因此挟嫌报复。并多次派御史去访察，想因此牵连义云。
前为汲郡太守翟嵩启列：义云从父兄僧明负官债，先任京畿长史，不受其属，立限切征，由此挟嫌，数遣御史过郡访察，欲相推绳。
He was first impeached by Di Song, governor of Jixun County, who said that his cousin, Bi Sengming, owed official debts. Sengming was originally the magistrate of the capital and was not under the jurisdiction of Dai Song. He gave Sengming a time limit to repay his debts, so he held a grudge and retaliated. He also sent Yushi to visit and investigate many times, hoping to implicate Yiyun.
