《旧唐书·列传·卷一百二十二》
每年应试被录取者，在朝廷排列名次授任官职，职事的权衡虽然由令狐腍做出决定，但取舍何人完全在于令狐滈。
每岁贡闱登第，在朝清列除官，事望虽出于綯，取舍全由于滈。
Every year, those who passed the examination were ranked at the imperial court and given official positions, and while decisions about official emoluments were made by Linghu Xu, the actual selection and rejection of candidates was entirely up to Linghu Chu.
